guitar picks, coffee mugs, beanies, caps, hoodies

Custom guitar picks.

Custom guitar picks or inserts for 45 records would be fun!

Not sure if this is doable, but custom guitar picks would rule!

If I could order custom guitar pics that delivered as much delight as your stickers, magnets, etc, that would be awesome.

A decent fallback to actual picks could be printing sheets of pick-grade plastic that customers could cut with a pick press (like Pickapalooza).
