This mega-sized 300mL liquid chalk refill pack is designed to top off the 50mL clip bottles - with up to 6 full refills! The innovative low-waste packaging uses 60% less materials, energy and resources in its manufacturing (industry first!). The lower weight and compactness also results in less emissions during shipping! Since this packaging squeezes down as it is used, it also reduces spoilage caused by air (oxygen) getting in. Nothing is worse than buying an expensive tube or bottle of liquid chalk, only to have half of it dry out before you can get to use it! Perfect for use on it’s own while bouldering or as a base layer for the ultimate grip on your sport routes!
