The Thumb Finisher!
This is a fun little tool to use at the end of a pinch/thumb session.
It offers light to medium resistance (depending on your strength level) and is not adjustable so repping out with it at the end of a session is an excellent finisher.

Fantastic piece, extremely portable, grip positioning variance and hanging weights off the end ring all provide more than expected. Need to get a second unit once back in stock. Strong quality build.

Thumb pump
Awesome little gadget. Light resistance, but with many reps it gives a nice pump. Great to take along when you need to kill some time. Very sturdy build quality. Great thing.
