When your baby’s ready to graduate to a toddler straw cup, these convenient silicone straw conversion tops are all you need. Designed to fit perfectly on your 8 ounce Nursh baby bottles, the silicone straw in these lids turns your existing baby bottle into a kids' straw sippy cup. The unique design of the silicone straw combines with your baby bottle’s existing silicone pouch for drinks. This straw is made of 100% silicone, perfect for transitioning from a bottle to a cup, giving your little one the familiarity they need while educating them on drinking from a straw. The rotating cover and valved straw included in this conversion top keeps the drinks inside the cup and off of your kid. This product is perfect for toddlers who are ready to transition from baby bottles or older children using our feeding supplies. What’s that? You only have 4 ounce Nursh bottles? Go ahead, carefully cut the straw down to size, we love a good parenting hack! Review: Get the boon accessories you won’t regret it. - These work so well! They do not spill or leak. I have not had it fall from more that 3ft. Probably the most leakproof cut I’ve ever had. I like the fact that I don’t have to buy a whole cup set but instead have the option to buy just the lids. This is economical choice as well as an environmental one. I started with bottles then sippy cup and now this one with a straw. I also have flat lids for storing their snacks. So I feel less wistful and more money on my pocket with the boon system that growers with them. However they are a little tough to drink out of. I tried it because my baby was having difficulty but within a few minutes she was fine. Overall great fit use and easy to clean. Review: Great next step! - These are great!! Having already had the Boon bottles from my baby registry, these are a perfect upgrade for baby who’s ready to move to sippy cup style! Love that they are a valves straw so no backwash and graduated drinking which allows for baby to not choke on water as they learn. Mostly spill proof though some does leak out of the straw a little but has been dropped on the floor and tipped upside down multiple times and doesn't spill! As an OT mama I love this option in place of a standard sippy cup ## Features - Silicone Sipping: The Nursh conversion top with a silicone straw combines with your NURSH bottle’s silicone pouch for drinks that only touch 100% beverage-safe silicone - Spill Proof Cups: These straw cup lids changes your baby bottle into a no spill sippy cup with a valved straw that creates a spill proof seal to keep drinks in the cup - Flip Top Straw Cup: These Nursh straw cup lids feature a rotating cover that helps keep the straw clean when not in use while keeping their beverages safe from spills while on the go - Easy to Clean: Rest easy knowing that these sippy cup lids are top rack dishwasher safe just like the Boon Nursh silicone shell, ensuring their favorite sippy cups are always ready for a new day - Toddler Cups: These sippy cup lids are for use with Boon Nursh bottles to create a transitional cup for your little one when transitioning from baby bottles to toddler sippy cups with straws ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08ZH9H35L | | Best Sellers Rank | #3,224 in Baby ( See Top 100 in Baby ) #103 in Toddler Cups | | Brand | Boon | | Brand Name | Boon | | Closure Type | Flip Top | | Color | Clear | | Customer Reviews | 4.0 out of 5 stars 2,279 Reviews | | Included Components | 2 Silicone Straw Conversion Tops | | Is the item dishwasher safe? | Yes | | Is the item microwaveable? | Yes | | Item Type Name | Silicone Straw Conversion Top | | Manufacturer | TOMY Intl. | | Manufacturer Part Number | B11498 | | Material | Silicone | | Material Type | Silicone | | Model Number | B11498 | | Number of Pieces | 2 | | Product Style | Straw Sippy Cup Lid | | Shape | Round | | Style | Straw Sippy Cup Lid | | UPC | 669028114986 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Boon - **Color:** Clear - **Material:** Silicone - **Shape:** Round - **Style:** Straw Sippy Cup Lid ## Images ![Boon Nursh Silicone Straw Sippy Cup Lid - Conversion Top for Bottles - Toddler Cup Top - Changes Baby Bottles into Cups - 2 Count - Image 1](https://m.media-amazon.com/images/I/61GlBOnUy2L.jpg) ![Boon Nursh Silicone Straw Sippy Cup Lid - Conversion Top for Bottles - Toddler Cup Top - Changes Baby Bottles into Cups - 2 Count - Image 2](https://m.media-amazon.com/images/I/71LQyQ9YRiL.jpg) ![Boon Nursh Silicone Straw Sippy Cup Lid - Conversion Top for Bottles - Toddler Cup Top - Changes Baby Bottles into Cups - 2 Count - Image 3](https://m.media-amazon.com/images/I/71EessZku7L.jpg) ![Boon Nursh Silicone Straw Sippy Cup Lid - Conversion Top for Bottles - Toddler Cup Top - Changes Baby Bottles into Cups - 2 Count - Image 4](https://m.media-amazon.com/images/I/71Ic4AzgTqL.jpg) ![Boon Nursh Silicone Straw Sippy Cup Lid - Conversion Top for Bottles - Toddler Cup Top - Changes Baby Bottles into Cups - 2 Count - Image 5](https://m.media-amazon.com/images/I/81D-ooeVk5L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: I have the 4 oz bottles, can i just cut the straws to fit or is there another shorter straw conversion set?** A: They don’t make straws for the 4oz bottles since the smaller size is generally used for younger infants. The straws have bite valves at the top so are more suitable for 9months + of age for which a child is usually using a larger bottle. To answer your question - technically you could cut the straw. **Q: Can this fit mason jars ?** A: No, the threads are different. **Q: Is this a direct match for the grey boon nursh?** A: the straw top fits all of the silicon pouch bottles (4 and 8 ounce or all colors). Our daughter loves them and it makes the bottles usable for a lot longer. **Q: Am I wrong Description states 2 pack but was only one in package** A: It should be two ## Customer Reviews ### ⭐⭐⭐⭐⭐ Get the boon accessories you won’t regret it. *by J***E on March 26, 2026* These work so well!

When it came time to transition my baby to a straw top, she would not use any other top. We already used the boon Nursh bottle since she was born so when I came across this top and I did not have to buy a whole new bottle was so nice. These are so easy to use and clean. The straw detaches for better storage. Great quality and the seal never leaked. My toddler loved to chew on the straw, and it was stretchy and durable enough to withstand her biting it. ## Frequently Bought Together - Boon Nursh Silicone Straw Sippy Cup Lid - Conversion Top for Bottles - Toddler Cup Top - Changes Baby Bottles into Cups - 2 Count - Boon Nursh Reusable Silicone Pouch Baby Bottles - Medium Flow Nipple - Silicone Baby Bottle Pouch and Nipple - Baby Feeding Essentials - Color Block - 3-6 Months - 3 Count - 8 Ounce - Boon Nursh Silicone Baby Bottle Nipples - Bottle Nipples for Boon Nursh Baby Bottles - Baby Bottle-Feeding Supplies - Fast Flow Baby Bottle Nipples - 3 Count --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/299104890-boon-nursh-silicone-straw-sippy-cup-lid-conversion-top-bottles](https://www.desertcart.pl/products/299104890-boon-nursh-silicone-straw-sippy-cup-lid-conversion-top-bottles) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-10*
