It’d make a great gift for just about any girl (teens would probably love it) and it’s very cheap - it sells for merely $10. The tail is made out of artificial fur and you simply attach it to the 30-pin connector. As a bonus, with it, no dust will get in there, so it’s not completely useless.
You also have three versions of the tail - a fox, cat and racoon. Along with them come three matching wallpapers. Check out the pictures below and hit the source below to get it.
