Rock Technologies MAG Liquid Chalk in 250ml bottles, supplied as a box of 12. A UK-developed liquid chalk that dries fast and keeps your grip locked in, in a pack size that makes sense for walls, clubs and shops.

MAG Liquid blends sea-water-sourced, pharma-grade pure magnesium carbonate with rosin for extra tack. It goes on smooth and dries to a fine, even coat that doesn't cake or flake. It's sustainably manufactured and bottled in recyclable HDPE, with caps and labels containing a minimum of 30% recycled content, so you're chalking up without the plastic guilt.
