The new Carry Case is precision-milled from a solid block of 6063-T5 aluminum. Inside are four fully cylindrical chambers, and the round form holds the shape of whatever you put in without compression. Each chamber is numbered one to four, CNC-engraved into the lid, so you always know what's where. Ten magnets hold the lid in place and keep you safe from unwanted scents. The base holds a spring-loaded compartment for the ones you want to pause and save for later.
