DIY Coaster Silicone Mold, Pack of 4 Resin Molds for Casting Eco-Friendly Sturdy Hexagon Square Round Mold Bottom Bracket for Casting with Resin,Concrete,Cement

These are some wonderful molds for coasters to use with resin. They are a thick silicone and usually peel off pretty easy, but I would definitely recommend using a mold releaser sprayed on them before pouring resin. The first pieces I made, I didn’t use any and they got stuck on the sides really badly and ended up messing up the mold and now all coasters I make have the spot where the mold got ripped on it. But they are so very nice coasters and they still look nice.

The largest square mold doesn't have the correct shape. I found out while pouring the resin. I'm really angry. Why are you sending such defective products to customers...

These molds work perfectly! Here is one of the coasters I've made using the small circle one. It was super easy to demold. The mold is thick and sturdy enough to not rip or tear when demoulding. Just make sure your resin is mixed properly and at the right temp in order to eliminate bubbles and air pockets. Also make sure you clean them thoroughly before using. As you can see the white dot, my mistake I also paint in my work space. Great product and highly recommend if you use resin!

Would definitely buy again. I'm a beginner, made my 1st coasters. Had no issues demolding. Sturdy material.

Just as described

Loves these molds they made my project come out so beautiful. I recommend you soaking them over night in soapy water I used dawn dish soap but u can probably use any soap easy clean up and wonderful cast🤙🏾🥰

I really enjoy working with these molds the only thing I don’t like is how they come all bunched up together in a bag and they loose their shape. I’ve had to re order them and I just work with what I have. I have to put something against the coasters for it to keep its shape.

Perfect
