The Dynamic Disc Grandma’s “dirt bag” contains a mix of rocks that, when rubbed together, create a “dynamic dust” that feels similar to rosin.

Approximately 4.5″ x 3″ in size.

Features:

• Super absorbent and easy to carry
• Retains drying ability for longer than other similar products
• Unlike other products out there, if these happen to get wet, they will dry out and be usable again in future rounds
