This is Bitchin! Get it! You will not be sorry. It might not look like much, but once you get this you will never go climbing without it. This is the BEST way to carry your extra chalk. No mess ever. Worth it at any cost. I just put a block or two inside, then I hit it with a big mallet a few times. Simple. I've had mine for years and I still think it is the most handy climbing accessory made. Sure dynamic ropes, sticky rubber & cams are nice. But you already have those. Your next purchase should be The Powderhorn!
