One of the major reasons we moved into making handmade dice was to be able to add cool stuff inside the d20. After we made the Skulld20 work our next task was to get the liquid core d20.
These are sharp edged, handmade dice with an inclusion so small imperfections are possible and the balance is not 100% perfect like any dice with an inclusion. The liquid core also causes them to stop rolling
Obviously as a handmade product supplies are super limited. If you'd like to get a full set of our handmade dice each month (at a discount) check out our handmade dice subscription.
