Sochi Yo-Yo Holder
This is a yo-yo holder by Sochi Company, a yo-yo accessory brand.
The yo-yo can be attached and detached with a single touch, making it easy to carry a yo-yo. The size of the belt can be fine-tuned to the size of the yo-yo you're carrying.
The string cutter section is also useful for maintenance.
This holder can be used with most yo-yos in the middle to full size range for string tricks, but there are some models, such as looping models and models with high edges, that cannot be attached to the belt.
