These things are incredibly light (0.9 oz), good sized (12.5" x 19"), easy to inflate/deflate... and they don't seem to agree with my head. I've a pack of three to give away-- only one has ever been inflated-- I tried to nap on it one day, and couldn't get comfortable.

A new three-pack will only cost $3.95, so reselling them seems asinine. If you're willing to pay me back for shipping them to you, I'd thank you profusely. PM me if ya want 'em.
