Just made my first batch and they worked very well. I think for resin they will last a long time because resin is not abrasive like cement. Not sure how long they will last with cement, but in the seller's defense they do advertise them for cement. My pieces came out of the molds very easily and the surface is very smooth as you would expect with a silicone mold. Review: Quality molds and selection - Nice molds with glossy finished projects. The assortment of shapes and inclusion of holders are a great addition to my mold collection. They hold their shape and wash up well.

You can use a vacuum machine to extract the bubbles (the best method), or spray alcohol on the surface to remove the bubbles. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BKZ6ZH2S | | Best Sellers Rank | #2,112 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #14 in Sculpture Molding & Casting Products | | Brand | LET'S RESIN | | Brand Name | LET'S RESIN | | Color | 18pcs | | Customer Reviews | 4.7 out of 5 stars 2,283 Reviews | | Item Dimensions | 3.15 x 3.15 x 2.36 inches | | Item Type Name | coaster molds | | Item dimensions L x W x H | 3.15 x 3.15 x 2.36 inches | | Manufacturer | LET'S RESIN | | Manufacturer Part Number | ELR00207 | | Material | Silicone | | Material Type | Silicone | | Model Number | ELR00207 | | Number of Items | 1 | | Number of Pieces | 18 | | Shape | Square | | Unit Count | 18 Count | | Warranty Description | 60 Days Money-Back Guarantee | ## Product Details - **Brand:** LET'S RESIN - **Color:** 18pcs - **Item dimensions L x W x H:** 3.15 x 3.15 x 2.36 inches - **Material:** Silicone - **Shape:** Square ## Images ![LET'S RESIN 18 Pcs Coaster Resin Molds Silicone, Coaster Molds | with Round Square Octagon Shape Holder Molds for Epoxy Resin, DIY Art Craft Cup Mats - Image 1](https://m.media-amazon.com/images/I/71SIWlljWnL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How come I can't use a heat tool for popping bubbles?** A: I think they are just afraid it will melt the mold. I still use a heat gun and haven't had any issues. **Q: Is a release agent needed prior to use?** A: I didn`t need anything to take them out of the molds. I'm guessing using a release agent will make them easier to release. **Q: Can anyone tell me if there is any deformation after receiving the molds?** A: No, they are well packed in the box without any deformation and the surface of the mold is smooth. **Q: How do you remove air bubbles in the resin if you can’t use a heat gun or torch?** A: Use 91% alcohol. It pops bubbles. Also you’ll have less bubble if you set your resin In warm water for about 10/15mins before mixing it. I either sit my bottles in a sink of warm water or I set my poured cups in a bowl of war water. DO NOT HET WATER IN YOUR RESIN. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality and value for the price. *by S***Y on February 17, 2026* I bought them to use with cement, not resin.
