AFUNTA DIY Oval Silicone Coaster Mold,2 Pcs Soft Flexible Oval Crystal Silicone Molds for Casting with Resin, Concrete, Cement and Polymer Clay - Transparent White

I ordered these after using a different brand that was sold out (the other ones are perfect but I only have two, so wanted more to make my production quicker). These arrived and the sides were a bit warped from being packaged in a soft plastic envelope. I let them sit and didn't have an opportunity to use them right away, and the molds appeared to straighten out. However, upon pouring jesmonite/concrete into them, the sidewalls on the long edge of molds didn't hold their shape so the edges of my finished pieced are uneven. Sadly, I didn't learn this until after the return period closed. I will recycle these and purchase molds from another company.

I love using these molds with concrete and gold leaf to make trays. They take about 6 oz (volume) of concrete. They are easy to remove and are very easy to clean. I have great results with this mold.

Justo lo que esperaba, excelente calidad y precio. Llegaron muy rápido también.

Crap molds, first time using them, demolded my epoxy and the mold was stuck to epoxy, ripped the mold trying to get them separated. Very disappointed, wrecked the mold and the epoxy tray.

Beautiful mould. Easy to use and demould. Great deal for 2 of them!
