So while the inside gel is slimy, you will not feel it on the outside. Hope this helps. Please contact us if you have any additional questions. - Natasha from Serenilite **Q: Are these available in larger sizes? I'm looking for something 2.75 to 3 inches.** A: Unfortunately, we currently only sell our tridensity stress ball bundle in one size which is 6 cm or 2.4 inches. We are working on introducing larger size stress balls in the near future. **Q: Where are these stress ball made?** A: China, of course.....! **Q: Can these be disinfected?** A: Not really, the outer surface is a synthetic material but the inner material is unknown. This may cause the Stress Balls to become soft/defective if thrown into a washing machine or even hand washed. You could potentially spray a washrag with 409/disinfectant and wipe them down however without causing any damage to their surface or inner materials. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***K on July 23, 2023* ### ⭐⭐⭐⭐⭐ Review *by R***N on May 30, 2024* ### ⭐⭐⭐⭐⭐ Review *by R***N on March 23, 2026* ## Frequently Bought Together - Serenilite Hand Therapy Exercise Stress Ball Bundle - Tri-Density Stress Balls for Adults & Grip Strengthening - Fanwer Finger Exerciser Hand Squeeze Ball, Hand Grip Strength Trainer Build Hand, Finger and Wrist Strength, Finger Extension Exerciser for Rehab, Arthritis, Carpal Tunnel - Pnrskter Hand Grip Strengthener, Finger Exerciser, Grip Strength Trainer (6 PCS),New Material,Forearm Grip Workout, Finger Stretcher, Relieve Wrist Pain, Carpal Tunnel, Trigger Finger, Mallet Finger and More. --- ## 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/103834020-hand-therapy-exercise-stress-ball-bundle-tri-density-stress-balls](https://www.desertcart.pl/products/103834020-hand-therapy-exercise-stress-ball-bundle-tri-density-stress-balls) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-11*
