I recently ordered this item for a friend of mine since he was looking for one for quite a while and frankly both him and I are dissapointed with the quality of the product for the price that was paied. looking at the image of the item you'd think that the pendant is of reasonable size, quality, and made of metal. but the reality of it is that the pendant isn't that large at all it's very small, so small infact that it dwarfs compaired to the plastic light up version that you get in the gurren lagann vol one collectors box. compaired to the plastic one the metal one is very tiny as I've stated before, the plastic pendant that comes as a freebie in the anime box set for vol one is 3" in length while the metal one is a 1 1/2". another issue is the cord the pendant comes on, it's so short that my friend could wear it if twisted the right way as a bracelet instead of a necklace which is rather pathetic because the only way we could see this being worn as a necklace is if it were placed on a 3 or 4 year old yet on the package it states "small parts not for children under the age of 14" on the back. any potential buyers out there who are looking for a metal version of the core drill necklace look else where cause if I'm right then this pendant is exactly the same as all the other ones being sold on amazon.com
