We needed something to add to a key chain for XH concert with beautiful mind theme. These brains are soft but durable enough for us to make holes through them to attach to the key chain. We love the results. ### ⭐⭐⭐⭐⭐ You are getting what you expect. *by C***P on March 24, 2025* I opened the box, I squeezed several of the brains. They were not hard. They were not way too soft. They looked like what was in the photo. They were basically the foam representation that I expected. They will not last forever, but they will be fun for a lot of kids this Halloween. ### ⭐⭐⭐ I didn't expect it that small *by K***I on December 26, 2024* I expected a palm size stress ball - this was more like a walnut size. ## Frequently Bought Together - Kasyat 40 Pcs Brain Stress Ball Mini Brain Shaped Stress Ball Bulk PU Hand Muscle Exercise Pressure Prop for Adult Improving Grip Strength Object Recognition Prop Mold Halloween(Colorful,Mini) - 64 PCS Brain Aesthetic Vinyl Colorful Stickers for Birthday Party Supplies Decoration Favors School Rewards for Kids Adults Teens for Water Bottles Laptop Birthday Party Supplies Decoration - BulbaCraft Brain Stickers for Water Bottle and Laptop - Brain Party Favors & Decorations, Waterproof Vinyl Decals, Science and Anatomy Stickers, Gifts for Women & Men --- ## 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.com.ar/products/368791222-kasyat-40-pcs-brain-stress-ball-mini-brain-shaped-stress](https://www.desertcart.com.ar/products/368791222-kasyat-40-pcs-brain-stress-ball-mini-brain-shaped-stress) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-22*
