Super cool 3D printed counterweight for 5A style yoyo. Can be converted into a keychain Official description: Wait! It's dangerous to throw in the tall grass. Pick one! These are 3D printed return top counterweights. Each one weighs about 10.5g. Version 1.1 is a revision to the original version. It can now be attached to the string in two ways:1) Wrap the finger loop around an indented black groove (the original way)2) Thread the string through the hole in the middle with a stopper button at the end. And of course 3) use it as a keychain! Monster Ball v1.1 can be used in any one of the three ways. All hardware included. See this video for instructions on how to switch between the three modes. Note: Core piece may be pink or white (but not visible after assembly), yoyo in picture not included
