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!

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.

These are great little molds for my resin projects. I waited to review until I had actually used them a few times. I have not experienced any issues while unmolding, but I do take the time to go through the process fairly carefully and slowly and always allow for a full 24hr cure prior to doing so. They came nicely packaged and the included care instructions were very helpful. Really enjoying these!

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.

These molds are very nice. These molds have a very solid feel--not flimsy at all, like others I've ordered. I could easily slide/move them around my work space and not worry about affecting the resin. They are perfectly sized and shaped. Other sets have been much too wide, using a lot more resin, but these have a more normal coaster size/diameter.

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.

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 were exactly what I wanted!! Worked beautifully and my coasters turned out amazing. STOP USING TORCHES OR HEAT GUNS EXCESSIVELY with molds!!! That’s the only reason they will stick. I hit mine with a heat gun for MAYBE 3 seconds and a good distance above the molds and I have had ZERO problems. These molds were WELL worth the money.

Great shape and size

Molds leave lumpy marks on resin.

Ich habe schon viele Silikon Molds ausprobiert, aber von dieser war ich sogar noch überrascht. Was sofort auffiel war die super Verarbeitung und Qualität des Silikons selbst.+ Silikon ist blasenfrei+ Festigkeit und trotzdem flexibel+ löst sich gut ab und ist gut zu reinigen+ schöne Geoden Form+ super netter Kundenservice

I used these to make resin coasters

I tried to cancel this after purchasing. I tried to cancel shortly after and they wouldn’t allow it. Now that I have them, I want to return them but it’s a hassle. I do not like these. They are of poor quality. I do not like the company making this sale go through. Poor business ethics and very expensive product for the quality.
