The Rungne Dynology Chalk Bucket stands upright on its own, which keeps it stable at the base of a boulder problem or clipped to a rope bag without tipping. The self-standing base and spill-proof magnetic closure work together so a knocked bucket stays a minor inconvenience rather than a chalk cloud. What Our Gearhead(R) Experts Are Saying:"The magnetic closure snaps shut between burns so chalk stays in the bucket instead of dusting everything in my bag on the drive home."
