Large, doual sided fands for helping you keep cool.
Bamboo ribs with paper inbetween, it's a fan.
PLEASE don't fight the fan. If it isn't opening, or it's creaking, then you're opening it the wron way. Lightly undo the fan until you are sure you know what yhou're doing. They're not fragile, but like all fans, but they only open one way.
Just the one design for now, it;s all we have, but more to follow for meatspace cons (found a stash of them while cleaning the store room!)
