This UK ETSY shop has some of the most unique/cute/kitschy "animal buttons" I have ever seen--and if properly aged/antiqued--have great potential https://www.etsy.com/shop/JustCreateCra ... itle_items

And the angel buttons have a lot of potential https://www.etsy.com/listing/468132380/ ... ?ref=hp_rv

They also carry the best metallic pens I have ever used https://www.etsy.com/listing/551745809/ ... ?ref=hp_rv
