Guanto 955 Lifting Chalk Block

Guanto 955 is plain magnesium carbonate, pressed into a block, with nothing added to it.

Pressed rather than loose, so it goes into a bowl and stays there instead of across the room. Breaks cleanly into quarters.

Plain magnesium carbonate with nothing added — no drying agents, no binder that turns slippery once your hands are wet. It wears slowly and visibly, so you replace it because you decided to rather than because it failed mid-session.
