Slimmy

My current wallet has begun the slow, painful process called 'falling apart', and I'm in the market for a new one. Queerty pointed me to the Slimmy, however, I'm a bit concerned that it's so slim that my money will magically disappear (must like all prospects for meeting a suitable boyfriend already have). Anyone have experience with this thing?It looks pretty hot, red's my color, and I'm dying to try one. (It's available direct from Koyono for $39 bucks)
