Overview
A six pack of egg shaped hand exercisers made from soft thermoplastic rubber, each offering a different resistance level for grip and finger strength work or general stress relief.
The set is aimed at both casual squeezing and structured hand therapy, with the range of resistances allowing progression from easier to firmer squeezes as grip strength builds. Everything ships in a storage bag with an instruction manual and gift box, which points to this being packaged as much for gifting as for personal use.
- Six stress balls at different resistance levels
- Soft, reusable thermoplastic rubber
- Includes storage bag and instruction manual
- Packaged in a gift box
Who it's for
Suits anyone building grip and finger strength, doing hand physical therapy exercises, or wanting a simple stress relief tool at a desk. Less useful for anyone who wants a single, fixed resistance ball rather than a graduated set.
