SakuraRetroModding has put an assortment of custom face buttons and shell stickers up for pre-order on Etsy. I've never been disappointed with a purchase from SRM. I have a blue V2 Miyoo Mini on the way and opted for "Pink Clear" face buttons which should be a pretty cool contrast of colors. Can't wait to receive the Mini V2 and buttons to customize it. Look what I found on Etsy: https://www.etsy.com/listing/1222104456/pre-order-shipped-the-6-june-4-buttons
