4 Pack Big DIY Round Coaster Silicone Mold, Diameter 3.94"/10cm, Molds for Casting with Resin, Cement

love the size of these molds. they are bigger than my other ones giving me options to make a bigger variety of projects with them. they are made of great quality silicone.

Great size and shape and love the lip on it. Each one holds about 2 oz of resin full. Perfect thickness to hold strong when curing and peels away easily if you do it right.

These coasters have become my favorite set of coasters, the lip prevents a cup or glass from sliding off. If you are looking for functional coasters, these are them.

I am a resin artist and what I appreciate most is the fact these were packaged in a box! Most molds, I order are shipped in a plastic bag, and squished together which warps and damages the molds. The fact that these came in a box show that they are thoughtfully packaged with the artist in mind. Highly recommend!

I made some really great coasters with these molds four pools. After that the resin began sticking to the mold and I was unable to take the resin out of the mold without tearing the mold. I would suggest you definitely use some type of mold release spray when using these.

These molds are of exceptional quality! They arrived in a box, so they were distortion free, and had a cardboard insert between each two, so they weren't smashed flat. The size is as stated, they have a nice sized lip to catch drips and the price was more than reasonable for the price! Great molds!

I love these coasters. Each time I’ve used them, my work comes out beautifully!

We made our own custom coasters - these were PERFECT.

These are excellent quality molds. The silicone is thick, with no imperfections. I'm seriously considering ordering a few sets of these to have on hand because they are that good.

I bought these to make resin coasters. They have a lip around the perimeter which is handy to contain spills and drips. I can't use them with my large mugs as they don't fit, but my regular sized mugs and glasses fit just fine. They do scratch easily which then shows up in your resin coaster so you have to be very careful handling them. Otherwise they are easy to use and the resin comes out easily once cured.

I absolutely love these molds! The only down side us i keep getting tiny air bubbles in the sides where irs hard to pop them.

They are excellent quality. Easy to use and a perfect size for a coffee mug or drink glass of almost any size. Live them.
