Not a toy for children, risk of ingestion of the steel ball.
This unique “desk toy” designed by JJW Concepts design studio is made from a machined aluminium anodized in a lovely light green color.
The outer groove is made for steel balls that can be pushed around in a satisfying way. The inner circle is magnetic and can hold screws, paperclips, or whatever else you need around the office.
Originally purchased as a gift, but never gifted (and never used).
