Heya! At the moment we're not offering stickers a-la carte. But, each individual shirt comes with its own set of stickers (2 sheets I think?). Recommend ordering some shirts - they're pretty cheap as far as merch goes! - and giving them to some friends, family, or donating them if you just want the stickers.
That will probably be the only way to get them for a while; possibly for at least the rest of the year. Everything is already made and packaged, we're not making any new stock to-order at this time. We'll see if there's anything we can offer as we get the socks mentioned in our blog, but no promises 🙂
