“Overall this has exceeded my expectations, perhaps because it's not until you have it in hand and can appreciate its heft and finely cast features that its quality becomes apparent. In fact, it's surprisingly heavy: about 60g.That's perhaps because I am used to handling LEGO... More things made of plastic! It's coated in a clear protective lacquer and the chain and keyring have a 'distressed' look. To some extent they cheapen the look of the overall item and I'd have preferred them to be nice and shiny like those on normal LEGO key chains.”

“The keychain comes in its own storage box. Securing it inside the box is a hard foam which keeps it snug. Taking it out, you’ll get a surprise as it is way heavier than you’ll probably expect it to be. Coming in at 61 grams, it’s quite heavy and I don’t think you would... More really want this with your keys. I believe it is made out of stainless steel as it doesn’t attach to a magnet. The back of the keychain has an engraving of the LEGO VIP logo as well as the legalese. The size of the keychain is pretty much the same size as a standard LEGO minifigure.”
