@alexandra They’re 3D-printed with this Prusament Galaxy Black PLA filament: https://www.prusa3d.com/product/prusament-pla-prusa-galaxy-black-1kg-nfc/

Black with little sparkles—some of my favorite.

The earring hooks are stainless steel and they clamp into the printed piece. Both are inexpensive!

Let me print off another pair when I have some time and I’ll bother you for your shipping address.
