Worth the price 👍 ### ⭐⭐⭐⭐ Review *by K***L on 7 December 2020* Product is tooo too good. I am fully satisfied with the product. But not happy with package. You can do something better in packaging. ### ⭐⭐ Review *by K***V on 11 July 2024* There are many bubbles formed. The quality of the cast is not very good if you are looking for thin casts and also, th thick casts dopesn't bend smoothly. If you are creating cast for a chess piece for example, you'll have to use cut-out technique, as the rubber doesn't bend enough to take out the piece ## Frequently Bought Together - SILOCZEST Liquid Silicone Rubber-LSR 140-1kg - Super Glue 15359 Single Use Epoxy Tubes For Metal --- ## 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.br/products/406512935-liquid-silicone-rubber-lsr-140-1kg](https://www.desertcart.com.br/products/406512935-liquid-silicone-rubber-lsr-140-1kg) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-04-24*
