Resin Adhesion to Molds Issue : Do not use a lighter or blowtorch to remove air bubbles, as this may cause damage to the molds, leading to resin adhesion to the molds during demolding and thus tearing the molds. You can use a vacuum machine to extract the bubbles (the best method), or spray alcohol on the surface to remove the bubbles.

Good molds for value
Good molds for uv resin and self leveling resin. Easy to remove projects from molds. A little thin so probably wouldn’t recommend fast drying resin as the heat could damage the molds.

I’m new to working with resin, but I absolutely loved making my own coaster sets with these LET’S RESIN silicone moulds! They’re super easy to work with, and the resin releases smoothly once cured. I really like that the set includes three different coaster designs—it makes it fun to mix things up and create unique sets. Great quality moulds and a perfect choice for beginners or anyone who enjoys resin crafting!
