SLAKOZYT25MM Rounded Six Sided Dice,20PCS Blank Acrylic Dice with Smoothed Surface White Dice Cubes Suitable for Games, DIY Stickers, Party and Math Teaching

These are blank six-sided dice and are great for custom dice or prototyping. I personally use them when I run roleplaying games for when I need some custom randomization without relying on a table lookup. The dice are larger than normal, but that just means it's easier to put content on each face in a readable way. If you're using stickers, the faces easily accomodate a 3/4" circle. I personally make a sticker sheet in photo-editing software and then use a 3/4" holepunch to pop them out and stick them on the dice. You can also use fine-tipped sharpies which works out really well. Either way, the dice last a very long time. I have other dice that I've used stickers on in the past and with weekly use, they're over 6 years old and still going strong.

My son is always coming up with ideas for games and trying to build prototypes. These dice are really nice for that purpose. They feel like good dice and with blank surfaces you can make whatever unique numbers or symbols you need for the game you're building. No complaints - these are great!
