I lucked out and grabbed one of these weird leather yo-yos from https://leatheryoyoshop-fe.stores.jp/ The whole yo-yo (and the matching counterweight) is made from leather.
They currently aren’t shipping to the US, but that will change when this pandemic is more under control.
This yo-yo is the “Depth 5” in a natural colorway. I’m using a LCW Nuts in a matching color too. The yo-yo is cool, but I really think the leather counterweights are some of the best goodies on the site. I like the LCW Nuts the best, but the square counterweight with the eye is pretty unique too.
