Mamba Metals’ Thumbbell knuckle roller is manipulated with your fingers similar to the way you would roll a coin. The Thumbbell can be used as a discreet fidget toy, a skill toy to perform tricks with, or a training tool to improve finger dexterity. 

The Tiburon features a unique finish that feels similar to shark skin.This finish is an excellent option for users in humid environments or those with damp hands.

The completely hollow construction facilitates lightweight play to reduce finger fatigue while still maintaining durability for everyday use. Thanks to its concave ends, the Thumbbell doubles as a worry stone to help relieve anxiety and aid relaxation. Additionally, the concave ends allow the Thumbbell to rest on flat surfaces without rolling away.

Small, medium, and large sized Thumbbells are available. Generally, the small size fits well for individuals with small to medium hands, the medium size fits well for individuals with medium to large hands, and the large size fits well for individuals with huge hands.

An alternative sizing method is to select a Thumbbell with a length that is closest to the combined width of your index, middle, and ring finger.
