Completely handmade in the USA using only professional (not synthetic) baseballs, these unique gifts are deconstructed, delaced, and then hand-stitched back together using extra-thick thread. Once completed, each keychain is hand punched and affixed with a brass rivet and steel o-ring to ensure the longevity of this conversation piece. My personal key chain is over 3 years old and is only getting better with age. Finally, each key chain can be hand stamped with up to three numbers or letters (please specify when ordering). Due to spacing concerns, two characters is optimal, but three can be done. I do not utilize synthetic baseballs for any of my products. In my experience, they do not age as well or last as long. In addition, they don't have the "story" or the "authentic feel" behind them. All of my products are made for the true fan by a true fan. If you get to games late and don't stay until the "fat person" sings, then my goods are not for you. Purchase from someone else if you don't know the infield fly rule, or you don't know who walked the Yankees off the field during Game 7 in 1960. Please note that I am limited to stamping only three characters (numbers, letters, or a combination of three) on one side of your key chain. Two sided printing is no longer available. Also, please note that these are made from used baseballs and, as such, will sometimes have marks from bats, infield dirt, etc. Let's Go! Let me know if I can make one of these unique it
