Delivery was quick. ### ⭐⭐⭐⭐⭐ Open immediately to verify contents are new and complete. *by P***A on September 19, 2025* First set was used and missing letters. I purchased new. Requested a replacement it arrive quick and was brand new. Letters work great. ### ⭐⭐⭐⭐⭐ Great addition to my apartment decor *by K***Y on June 4, 2020* I used this product for a letter board wall in my apartment. I was a little nervous at first that the size was going to be too small but it ended up working perfect and saved me quite a bit of money from what I found online at other retailers. My one complaint was that all the symbols in the package are red which I wasn’t a fan of but I understand this is used more for business purposes and to catch people’s eye on the go and not for home decor lol. Other than that I LOVE it. ## Frequently Bought Together - Sign Letter Depot 4" Letter Printed on 5" Flexible Panel for Outdoor Signs - Changeable Portable Sign Letters - Thin & Flexible Assorted Changeable Black Letters & Red Numbers Included, 270+ piece Set - Changeable Outdoor Sign Letters 6” Portable Flex Letters 279 Count Helvetica Font 7” Panel --- ## 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/26657192-4-flex-changeable-sign-letters-on-5-clear-panels-black](https://www.desertcart.pl/products/26657192-4-flex-changeable-sign-letters-on-5-clear-panels-black) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
