15 Pieces Crystal Resin Molds Pendulum Silicone Crystal Molds Include Pyramid, Round Cone, Sphere, Triangular Cone, Multi-Facet Gemstone Cube Resin Holder for Jewelry Making

There are great for beginners, small scale models and jewelry. Easy removal good quality.

The crystals were hard to pour the epoxy in. I did not like pouring into the side of the mold. I made a mess of it. They were easy to remove but these molds are not for beginners.

Came quickly seems like good quality. I haven't had any issues with the molds.

crystal molds were hard to get resin out of

I used these for epoxy resin (and a test with some leftover candle wax) and for the cost, it gets the job done. If you want high-quality molds I wouldn't recommend them, but if you want to get something cheap before investing in something pricier it's a fairly good set. They're on the small side (as other people have mentioned) and some of the tips don't seem to work right (for the cone, pyramids, some of the gem-shaped molds).I also had trouble getting my resin out of the small-but-long molds, but putting them in soapy water worked like a charm.

The molds came a little warped or distorted in different areas. I tested the gem twice. I bought them because of the small size of the molds, but they don't really make what's advertised. I do like the small rectangle one from this set, it worked well. I showed in the photo the warping on the two gems I made. That's supposed to be the bottoms, but they look dented.

The silicon of these molds for some reason stuck in multiple places to all of the resin pieces I made with them. The molds had to be damaged to remove the projects and I will have to spend a great deal of time sanding off the silicon chunks that are stuck to them to save them. I think if the mold was waxed beforehand, it would be OK, but I didn't know that going in, and also I've never had this problem with any other mold I've used. The silicon is also VERY thick, which makes getting the pieces out almost impossible in some cases (like the thin, narrow bars), even if they weren't sticking.

Too hard to remove
