Perfect item, poor packaging.
Color: Dark Apricot, Color: Dark Apricot
Bag is cute and exactly what I ordered. Lots of space and usual functions are in great condition. However.... my item was delivered in a plastic bag taped poorly. Bag was folded and so it now has creases due to the fold. I am not happy with the delivery. The item is in good condition otherwise so I will be keeping it since I need it for work.

Tiny!
These studs are about a quarter as large as my other studs! They are way too small and will come right out if your piercing hole is larger than a pin-prick size! Not a good product at all!!
