4 Pack Hexagon Silicone Coaster Molds - Silicone Resin Mold, Clear Epoxy Molds for Casting with Resin, Concrete, Cement and Polymer Clay

So far, I’ve found these molds to work quite well. I’m using them a bit differently than they were intended — using the open face as the top instead of the bottom, which requires some more work after the mold. I notice the sides have a tendency to bow out with the weight of the epoxy, so I place some straight edged blocks next to them to reinforce the sides and it takes care of that issue. I’ll probably buy more if these hold up well over time.

These were a purchase in addition to the sample molding set I purchased. The hexagon shapes couldn’t be more of a thank you purchase especially for the quantity you get on the price of these. The molds are phenomenal and hold up well. Worth it.

These are easy to use with resin. Perfect mold every single time, and very easy to demold. They're not too deep, and are great size for little trinket trays.

These are pretty sturdy molds. The only reason I have 4 instead of 5 stars ⭐️ because the round mold is much smaller than the other two. It will only hold a small water bottle, not a mug or anything bigger.

I recently purchased these coaster molds to add new products to my small business shop, and I’ve made 2 orders with them so far. The molds are accurately measured, perfectly cut and the bottom cross makes them supportive for the resin I add. The coasters are shiny and thick,, very good quality.

I love love this molds. I ordered some other molds from a different company and was disappoint but these molds are the BEST. The resin doesn’t stick in the molds and it’s easy to lift the resin once it harder. I LOVE IT, I will be ordering more molds from you!

I just received my second set of hexagon molds. The first set ripped terribly when removing my silicone. The second set is being returned right away. They are covered in dirt, hair, and have clearly been used before.
