These are an experimental design and will most likely never be made again.

This listing is for a single "XL" d20. (21mm) 

These dice were handmade by me. Since these are hand crafted ttrpg dice, you can expect to see some imperfections, therefore they are not perfect and may have some flaws although I do my absolute best to minimize them. These dice contain micro bubbles and sanding/polishing marks/scratches may be visible.
