LET'S RESIN Resin Molds 18Pcs Pendulum Crystal Silicone Molds,Multi-Facet UV Resin Jewelry Molds for Quartz Crystals Pendants, Necklace

So far so good. I've created about 5 resin casts each so far and the molds are still in decent shape. I haven't really used the bonus metal things that came with it though. I just pour in my resin in two steps, then drill out the hole to the other side on some of the molds since the hole doesn't go all the way through.

Let your imagination flow

The media could not be loaded. I’ve been using these silicone crystal molds for a while, and while they’ve produced some nice pieces, they’re already falling apart after only a couple of months. I’ve gotten a fair amount of use out of them, but I expected them to last longer.Another issue is that they’re really difficult to demold—without silicone spray, they can tear easily, which is frustrating.UPDATE: After posting my review, the manufacturer reached out to me and gave a full refund. If you have an issue, you can count on them to help you.

A nice variety of shapes and sizes, and fairly easy to de-mould.If the resin used is a little thick or contains occlusions like mylar flakes or large glitter pieces it is hard to get into the very thin tips and edges without bubbles.I do really like how they all stand on their own so they don't require any extra support.Some of the threading holes do not go all the way through so they may require a little extra drilling, but that's not a big deal.

I love how easy to use these crystal/gem stone molds are. Easy to clean up afterwards as well. The mold is thick but not too thick. The size is about the shape of a palm of my hand. Very good quality in my opinion.

They work well and the resin pieces come out beautifully.

This was a gift for my son. He can't wait to start using it. Took it out of the package and was so pleased with the different shapes.

I was asked to be part of an art installation coming up this spring.The only issue was that my art is normally big stuff. This install requires that every piece of art fit into the diamond of a City owned Chain Link fence. Hmm. What to do?I got same of my smallest items and modified them to fit and they look great. I had never done jewelry before but thought I would try these. When I posted the to the other artist, they all said to make a bunch of these to add sparkle to the whole installation.I'm getting the hang of it now and it's fun.The molds are thin but have their one built-in stands to assure the opening is straight up. Most have a pin to create a hole for the wire but I would almost rather drill my own. They do work nicely though.Air does get trapped so I suggest you fill to just above the tip and then use a toothpick to pull the bubble out. Doing that, I had zero bubbles.If I do start selling them I will sand and polish but for the installation, I just used my trimmer to shave the fill line. That way it keeps the full sparkle which is what we are gong for.I am really happy with these and as long as you drop them into a warm soapy water bath to remove they should easily get 20 pours out of them. So far I have 5 ours out of them and have yet to break one single hole post. I know that will happen soon but not a show stopper.
