Over thinkers this one is for us! A funny reminder to put on your keychain if you love to over think everything. Don't think too much about buying this keychain though! Hehe. This would be such a fun stocking stuffer! This fits perfectly on a set of keys and is 2.83" x 0.75". It is durable, waterproof hard acrylic with a clear snap closure and a stainless steel key ring.
