Review (4/5): good enough
I loved these, very convienent.... only problem is the thing that makes them most convienent (the keychain case) is extremely defective. the case won't stay shut!!! i got around this by taking one of my really small clear elastic hair pony tail holders... the kind you get at walmart in a pack of like 30-50 for a dollar or two... and i used that as a rubber band to keep the case closed... it worked :)
aside from the case not closing (and the fact that i order two sets, was billed and payed for two sets, but only recieved 1 set... oh and also I didn't get to choose the color I wanted) yeah, aside from all that i liked the product alot :)
