Thanks!

also, I CAN sort of attest to the shit with acorn press rn.

a friend of mine (stantler) put in an order with them for charms and they only arrived like two days before the con and their communication just kinda fell by the wayside.

though im not sure if its just screwing over lesser known vendors, from what i understand more notable people in some fandoms were able to get their orders and correspondence a lot quicker than she was.

I recommend zap creatives and can show you examples via the charms I've received.
I would NOT recommend acorn press at the time since they have gone very downhill do to overload of orders and rushing things. [info taken via an artist alley group I am in. I am welcome to link you to that as well]

Good luck!

Thanks! Zap creative looks like they only sell charms per/50 and I dont really wanna sell fanart to get rid of charms meant for 2 XD.

There is also an option to buy just 1 charm under some sizes / types!
I know the clear acrylics have it
