Because sometimes you just have to be honest and practical. Aluminum is very lightweight, but very sturdy. ✰ Key chain is lightweight aluminum, 1/2" x 2". A 12mm split ring is attached, so you can add it easily onto your existing key ring. If you want the larger, full size split ring, just leave me a note at checkout. ✰✰ Want your key chain to say something else? Feel free to contact me about a custom order.
