On my last trip to Walt Disney World My friend and I went to the HUGE Disney Store at Downtown Disney. We both found cute charms for our cell phones. Hers was Tinker bell Pixie dust and mine was Pirates of the Caribbean. The charm it's self is about half an inch by half an inch. It is a skull with cross bones behind the skull. The skull is wearing Captain Jacks Sparrows red head piece. There is a small "bronze" bell dangling with the charm as well. It's not annoying by any means while talking on the phone or just walking around. It does "tink" a little but most of the time I do not even realize the bell is there. It is not a loud ringing bell. The thread on the charm is about 2 inches in length and very sturdy. The charm and thread combined are about 2.5 - 3 inches in length.
I have not had anything go wrong with my charm. It has been over a year and it still looks as great as it did when i bought it. My friend on the other hand lost the pixie dust out of her charm by the time we got back to her car after purchasing.
