Handmade liquid core 30 mm D20: Oil spill

This 30mm D20 was made with resin, a liquid core and blue foil. This D20 was made in a pressure pot, with my own mold, font and logo. A liquid core is a small glass orb that I've filled with mica powders, mylar and water, then sealed with uv resin before casting it in the D20 mold. This D20 doesn't have any bubbles but might have some small quirks. Please look at the pictures for the quirks. Also please note that the quirks don't affect the accuracy or balance of the die and that they are purely cosmetical
