Rock Technologies MAG Green Fine-Grind Chalk in a single 10L/2kg tub. The classic fine, dry grind climbers rely on for a secure hold, sourced from sea water and manufactured in the UK, in a size that will keep a chalk bag or a chalk station going for a long while.

MAG Green skips the environmental cost of traditionally mined chalk without giving anything up on grip. The tub is moulded from recyclable HDPE with a minimum of 30% recycled content, so it's a genuinely sustainable way to stock a gym, wall or shop with loose chalk, and the empty goes in the recycling rather than landfill.
