Color: Pyramid Mold
I need more resin! This is a great mold. You can make gigantic pyramids! I've made too many already. Luckily, I have friends that like to take them. Very durable. Beautiful results. Thick silicone is going to last a long time. Easy clean up and setup.

Color: Pyramid Mold
I purchased 2 of these pyramids. Used both once, no problem. Used them second time and both molds stuck to my resin project. Both were ruined due to the silicone melting and sticking to 3 sides of the pyramid, in the same spot! Can not get off the melted silicone. Very disappointed because I wasted resin and gemstones in the resin. I see i am not onlying one this happened to. Seller.... i followed instructions and added mold release. I think these molds are not heat resistant and that they degrade after first use. I also think that leaving resin in mold for less time might work better as the resin is not fully hardened. Have used other molds and have had no problem. Well that was a waste of 40 + dollars. Wish this seller would have warning. Everal weeks later....I sanded down the pieces and re-resined them. They look great. Now for apologies. ... to the seller.... they refunded me the purchase price which shows me they are well intentioned sellers. I found out that the mold release was the issue. Not the molds themselves. I am truly sorry for jumping to conclusion. I ask that all readers learn from my mistake and embarrassment.

Color: Pyramid Mold
We're new to epoxy Resin pouring, so we needed a mold. I looked at a lot of smaller molds, but who needs an ashtray anymore? I figured we could easily make tiny pyramids with this, & with the flexibility to make huge ones, too. I love that there are two molds, as hubby can have one, and I can have the other. He made solid pours using the plastic support base, which is perfect. I made a foil tape & cardboard support for the edges of mine, to allow for a hollow pyramid. Both worked perfectly. The edges do rise up a bit - just like water, so when you unmold, there's a hard ridge around the top part. I found a long straight file worked wonders for getting rid of that ridge, without scratching up the part. Made very fast work of it, too. Pros: + Both our molds released our projects easily, by simply turning them inside out most of the way. I did not want to ruin the tips, so I didn't turn it all the way out. (I used no release agent, just washed & dried.) + Both molds were a little bit dusty by the feel - inside, so I washed them with mild hand soap and water. Worked great, and they felt very clean after. + I found it hard to seat the pyramid into the plastic support base, at first. Then I slathered a tiny bit of soapy water inside the plastic part, and whoosh, the mold slipped right in there, and seated perfectly. As it dried, it welded itself to the base, which is good, because it's not gonna get bumped out of position that way. To release it later, I just wetted my hand and pulled around the top edges - letting water drool down between the mold and base, and whoosh, it popped right out, easy peasy. Cons: I don't really have any yet. Perhaps later, if they scratch, or tear, that will be an issue, but so far, we're delighted. I did find them pretty pricey, for what it is, but no moreso than any of the other mold options. At least this one is big enough make something of use. (though, not much use. : ) TIP: Be sure to use a toothpick or something to get the air bubble out of the tip, as soon as you start to pour. Our first test - the clear one, has a divot at the point, because there was an air bubble we didn't see. Too bad.

Color: Pyramid Mold
So much fun. Easy to pour into and easy to take out. Very thick and durable. Its two of the same sizes, but it looks like you control how big you make the pyramids. Nice set up holder for the molds.

I don’t have a picture of the final resin product because I’m not finished with it yet, but as you can see, the molds are as described! They are durable and flexible too! Cleaning it is very easy because any resin that dries on it comes right off.

Color: Pyramid Mold
I wrote a really excited, positive review after I made my first pyramid. It literally was perfect - pics shown. I am back to revise it. I finished my 2nd pyramid today. I used all the same materials as the first, to look almost identical. So I followed everything the same, same measurements and process. I used the 2nd mold that came with this order and this time I had multiple places where the mold stuck to my work pretty badly. Seeing other reviews it makes me wonder if, when not user error, there are some defective molds. Frustrating since it costed me about $70 in supplies and destroyed the 2nd mold.
