CROWNMADE Resin Coaster Molds, 4 Pack Geode Coaster Molds for Epoxy Resin, Coaster Molds for epoxy Resin

Amazing quality & amazing price! I've never had a single issue with these molds. I do a tun of floral preservation coasters and these are by far the best quality coaster molds I have ever used. They are thick & sturdy and although some reviews say they had an issue with resin sticking to the mold after using heat, I have never had an issue and I use a heat gun every time. I hope they come back in stock soon & I am looking forward to purchasing more molds from this company!

I love the size and shape of these. I understand there a reviews that say otherwise, which are valid of course, but every single mold I received was flawless. I've used them at least 20 times now, and they're still as sturdy as before. All of my molds have been easy to take out, and are shiny and smooth. I also appreciate being able to decide how thick I want them. Please restock, these are the best molds I've come across!

Perhaps the best quality molds I’ve ever owned. Don’t bother with those cheap molds you will only be replacing them after a few uses. These had like rigid silicon that’s thick and sturdy.Be sure to use release spray before pouring resin to be sure it doesn’t take chunks out of the mold. These are pricey but I assure you they are worth the money.

The first 2 sets of molds I ordered had a thick lip around the top. While the second 2 sets didn't. But all the molds where thick and good quality and deserve 5 stars. The first and second round of coasters I'm made for my niece's wedding came out of the molds easily with no problems. But then I noticed that there were a lot of bubbles in the clear layer of resin. So for the third round I removed the bubbles with my butane torch. I think I may have went too close to the molds because only 1 out of 16 came out of the molds without sticking and tearing the molds. 😥I'm afraid to continue using the molds for the rest of this project (I'm making 96!), so I ordered 4 more sets. I will TRY to be more careful about removing the bubbles and stay away from the sides.

Love this brand! Thick and good quality molds. After using different brands I’ll stick to these. I have used a heat gun with no problem, easy to wash and use.I saw this brand when I started experimenting with resin and was hesitant to buy them because I was on a budget so I ended up buying different brands but they are all so thin and flimsy that deformed so I can’t used them after few uses... I finally bought 2 sets of these geode molds and their square mold set and love them, I regret not buying from this brand before. I’ll definitely be waiting to buy any other molds this brand makes!

Love the shapes of these molds, however, the first set I bought ended up with a couple of lil holes in bottom of mold. As a result, each time I use these, the resin gets I. Those holes and I have to sand the coasters down to get rid of the bumps where the surface isn’t even. Then I have to recast with resin to hide the sanded surface. Great shapes, seem sturdier than any other coaster molds I’ve bought and used. Disappointed about the holes in my first set but like the shape so much that I purchased a 2nd set. Have used 2nd set several times now and haven’t had any issues at all.

These arrived on time and they are much better quality then I thought. The molds are deep and each one holds 3oz of resin. I like the thickeness with 2 oz of resin but I am happy to have the option. I havent had any problems with demolding whatsoever! My coasters come out shiny every time! I love these. This is my first time using molds. I used to make coasters with ceramic tiles but these are so beautiful and I cant imagine going back! You wont be disappointed if you purchase these.

I've been a resin artist for four years and a mold maker for 2 years, and I can attest that these molds are amazing. So many of the molds you find on amazon are flimsy and made of paper thin silicone. The silicone on these molds is thick and sturdy. For all the reviews that complain that the mold stuck to their resin piece, that's entirely user error and not a poor quality mold. If your mold is sticking to your resin then you've applied too much heat and fused the silicone to the resin. A silicone mold is not going to just stick to resin unless it was melted to it with heat.
