LET'S RESIN Bookends Resin Mold, 1 Pair Geode Book Organizer, Large Silicone Crystal Epoxy Mold for Books, Desktop Organizer, Office Home Decoration, Gift

These are smaller than I expected but great quality. I can't wait to start making bookends with these.

I used this mold for the first time and it worked perfectly. The mold didn't stick to the resin. Shipping was as described. I'll order again from this vendor.

BEFORE YOU RUIN FLOWERS AND MOLDS CASTING WITH EPOXY—— Please do your research. Tons and tons of research. The crap you craft with from Hobby Lobby isn’t going to be what you want to use for this, you’ll burn your flowers and these molds. (See that review with the purple roses)Get a resin meant for casting, pour in layers to avoid over heating and flash cures and burning spots in your delicate flowers, make sure every ounce of moisture is COMPLETELY out of your florals, and if you can’t afford to get a different epoxy- at least spend $10 on a mold release spray and still DO NOT do all of this in less than 3 pours if you’re using anything other than epoxy designed to do that. If you wait for the epoxy to completely cure between pours, you WILL see lines from each pour when you look through the side so if you need to be mindful of when you can mix and pour, be aware of that.These molds will work perfectly fine if you know what you’re doing.Have fun but don’t ruin yours or someone else’s flowers and a brand new mold thinking one resin fits all; it doesn’t.

I used these to cast table numbers for our wedding. Added concrete pigment to rockite and they came out beautifully in these molds.

4.5 stars only because one of the molds was slightly warped, making the inside edge not flat.

The media could not be loaded. I did not need a form fitting container to keep the molds intended shape. It’s a good quality strong mold. I didn’t use the soap and warm water trick to remove my piece but you could. Highly recommended.

I used this mold to encase someone’s wedding flowers! The molds are strong and durable. They did not bend out of shape during the pour at all. Easy for me to demold!

The media could not be loaded. I really liked these molds when they arrived. They seem sturdy and good quality. After I used the mold for the first time I noticed a slight curve in my finished piece in what’s supposed to be the flat side. These are bookends… so the flat side needs to be flat, you’ll notice in my video when you push the two halves together they do not touch in the center, making the slight curve more obvious. Really disappointed that when I tried to push them together they look really flawed because they don’t touch in the middle. Not sure how to go about fixing it. I wanted a perfect half circle.

Very good quality molds
