Genshin Impact buttons currently come in only one size: 1.5" (38mm)
You can choose between 5 portraits and two chibi pairs, or buy a set.

I will expand the selection, and add more buttons when I've drawn more chibis!

If you need one of these designs in smaller or larger though, or as a round keychain, pocket mirror, or magnet, please do let me know.

This is a FAN MADE product, not official merchandise.
