I have a brand new 7gypsies ATC rotating holder for sale.
See it here:
$23, includes shipping (USA, internationals pay actual shipping) and 50-pack of refill cards. Brand new, I took it out of the box, but never used it (it seemed like a good idea at the time!), so I am selling it. Email me at firstname.lastname@example.org if you are interested! First come, first served!
