Juanya 19 Styles Silicone Resin Casting Molds Resin Dice Molds, Polyhedral Game Dice Molds Multi-spec Digital Letter 3D Silicone Molds, Epoxy Resin Dice Molds for DIY Table Games

Please buy mold release. Don't try to cut corners like I did, or you'll find yourself cutting the molds off of your dice. Great variety of sizes. Perfect for making d&d snow globes.

I have tried every trick I know to get rid of bubbles forming at the top where you place the lid. Every angle of the dice comes out super clean and sharp without bubbles, but the top is hit or miss. I can usually get a perfect surface in the lid side 1 out of 3 casts. I start by spraying a little 91% alcohol into the mold before I pour the resin. I bring the resin all the way to the top. I do not place the lid on immediately. Instead, I wait until. any bubbles rise to the surface (around 30 minutes) and spray that with alcohol before placing the lid on, using a toothpick to pop the edges into place. Then, I set the mold where it is not exactly level to encourage any trapped air to move toward the hole in the top. about 5 minutes later, I will drip epoxy into the hole using a toothpick or a dropper until the hole is covered. Then I level the surface where the molds are sitting and leave them to cure. Then trim and polish if there are no air bubble holes. The numbers are NOT on the wrong side... you have to flip the lid around to the correct side...

Finally got a chance to use them. After mixing my resin (my bad here, shoulda looked first) found I was missing the smaller numbered d6, the smaller d8 and the lid for the larger d8. The pipettes are pretty much useless as they crack on the seam right away. They are cheap, and worth it. Good practice molds, I guess.

I love the variety in this pack, but some of the moulds are silly/unbalanced. The d24 mould is so cool, but is poorly crafted so that the top has one much larger side, which throws off the die's balance, even with dremel/polishing.I would recommend this if you are looking to make a variety of different sizes/variations of a set of seven. The massive d20 mould was the pull for me!That being said, be careful when removing from the moulds as they're a bit thin in places and a few of mine have started to get minor tears at the top (still usable, but have to be careful).

These are well made molds but using them is more expert mode than we expected. Bubbles are very hard to prevent and even small bubble ruin the face of the dice. You need a vibrating pan, special pipets, silicone stirers, a hot-water bath, and a lot of effort to have any chance of success. To ensure they come out correctly, you have to take great care, pour the molds, let them sit, debubble, resin the lid, then very carefully put the lid on after filling. Even then you really do need a vacuum chamber to get them to come out perfect. This is all normal for resin casting but just be aware this is not just a "pour it in" beginner level craft like resin molds with an open top where you can just heat smooth the surface.

This mold releases well but it's difficult to fill completely and to close the top.

These are definitely a hard mold to learn and will always, ALWAYS get voids. They don't sit well in a pressure pot and the resivoir is so tiny that massive voids are a common occurrence. You'll spend more time sanding than you will actually making the dice. I'd recommend saving up and just getting a slab mold.

Forcing me to write a written rivew no thanks Amazon.

Bought this set cos I wanted to try resin casting and make some dice sets for myself, on a budget. I had very low expectations after reading the reviews and have to say, they are on point. The regular dnd molds are okay, but it IS a stolen design, so these made the sharp edged dice that you will see pretty much everywhere on insta. The biggest disappointment was the big d20. The packaging is a simple film and when they packed this product with the rest of my order, the molds ended up getting squished. The big d20 took the blunt of it, and the result it pretty disappointing, it came out warped. The mold is also in itself not very good- the cap is bigger than it should and it barely slots in, which ended up warping all the faces near the 1 (which is the cap). You can fix the most of it with sanding but the numbers will suffers from it. Oh and the numbers are also in a different format, so forget the super cool insta-worth finish of the regular dnd set.I have not tried any other molds, aside from the smaller d6, which again was pretty disappointing. Being a rounded edge dice, you'd expect they would round up the edges of the cap, but, thats not the case. So I have the 6 face with rounded edges, and on the opposite end, the 1 face with all sharp edges. I have not tried sanding it down yet but I doubts the result will be good. I will most likely have to exacto-knive it and sand it, which is not ideal.I don't think these molds will endure the test of time. You really have to pull and stretch to take the dice out, so they will probs snap or warp at some point. For now, I'll improve my technique so I can get as little bubbles as possible and eventually, make my own molds :)

Die Würfelformen sind sauber verarbeitet und die Deckel passen auch einwandfrei. Selbst die großen Würfel sind am Schluss einfach aus den Formen zu entfernen

These work nicely and produce ok dice. The materials and quality are reasonable value for the price, but this style of mold is just hard to use without creating lots of bubbles. Good value if you are looking to try it out, but if you decide you like making your own dice, expect to become unsatisfied with these after a few uses.

I discovered that the D20 was broken after I pourred resin in it, resulting in a lot of resin on my table in the overnight. Clearly not recommand.

A lot of the reviews I read mentioned that the lids were messed up or difficult to get on.The lids have a tooth on them and you put the number side to the inside of the mold, which seems really easy to understand...The lids are a little hard to get in but once you get the hang of it, it's much easier and they feel really secure and flush which is what you want.I also didn't have any difficult matching which lid goes with which mold, just pay attention to the size of the numbers, and process of elimination. If it's difficult just take a sharpie and mark the ones that match so you know they match.These are nice molds, good structure, can't wait to use them and make some dice. If you have worked with silicone molds before you'll definitely have no problems.
