Hey Alfred! I chose Button pins over Enamel pins with this project was because of (a) the cost factor, and (b) the fact that I haven't made any enamel pins before.
Plus folks really liked the stickers last time, so they made a reappearance.
However, if this project is successfully funded and there are some leftover funds for further R&D, I was planning on making some enamel pins as a test. And if they turn out good, I'll certainly give you the option of having one :-)
Thanks for the update. I was hoping the pins would be pins rather than buttons. They look nice in your presentation, but would be awesome as a pin...I’d actually choose your design as a single pin over a collection of stickers. Might just be me but your character designs are worthy of something sturdier and more permanent I feel.
