Easily create your own dice for game night with these clear silicone dice molds.  Handmade by Alberto and Tania at House of Molds in Italy, these hand-poured, clear silicone molds are made to last! 

Choose individual molds from six unique styles:

  • D6 dice mold 16 mm X 16 mm 
  • D20 dice mold 20 mm X 20 mm 

Highlight the numbers with acrylic paint after demolding.

Each mold includes a split on the side to make demolding cured dice easy.

These molds are sold individually. Buy more, save more with the complete set of 7 dice molds.

Why does the clear silicone matter?  It allows you to see exactly what you are doing, whether it's removing bubbles or placing charms into the mold.  Being able to see through mold means you avoid mistakes!

Resin crafters will need to finish the dice post-demolding to get a perfect edge.  Beginners should expect to use these molds several times to learn how to get perfect dice.

Customer Reviews

Very pleased

I bought this as my first 3d model with the intent to make dice for my gaming group and friends and I am very please with it. The inside is nice and smooth and the dice come out very shiney and polished with very little finishing work needed.

Loved it!

I have used this mold many times, its easy to use, and has survived many castings, even when i failed to mix the resin it still came clean super easily!


I received my d20 mold about a week ago. The first casting was clear and beautiful. After that, I realized that my regular resin (polyester) was probably not the best for that. I asked for feedback and the Resin Obsession crew gave me lots of helpful suggestions.
I do have one concern - the mold is starting to tear a bit, no matter how careful I am. I've made about 6 dice so far, so I am concerned that it may not stand up to the abuse I'll end up putting it through. (I own my own business, so I pour daily.)

Make Great Dice!

I got a set of these molds and they work fantastic! The dice come out looking polished and shiny, and the molds themselves are sturdy and well-made. I did have to purchase some plastic injectors to get the resin into the tiny openings, though!

Good but not perfect

These produce good quality casts but the durability is not very good. My first set lasted about 2 months before they were no longer usable. Even mild heat to warm them up for casting yellowed the molds so they couldn't be used to cast UV resin. If well cared-for they make beautiful dice.
