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.


This mold works great! Very easy to use and feels nice and sturdy.
