Krypto-lite Cocoons are modular, multi-function devices. They can be used to display your favorite Starlingear (or similar style) bead or they can be used without the center shaft and be utilized as a pendant, key fob, bag marker, or any other use you might think of. Cocoons are machined out of 3/8" solid round stock. They can be produced in any metal type. The bottom piece is approximately 1.25 inches in length with perforated style holes or slotted windows and a center hole that is machined to accommodate the included vial filled with v10 glow powder or a 3x23mm tritium vial (not included). The top is approximately .375 inches in height. The optional center shaft is made of titanium tubing and can be made in any length to accomodate one bead or several. These utilize the same nesting system as the Krypto-Lites and come with tubing to protect the vial and allow the user to change colors at their leisure. The kits come complete with card, instructions, tubing, and an o-ring. The o-ring restricts the bead's rotation on the post and keeps it forward facing while being worn. It also acts as a safety catch in the event of accidental separation of the lower body from the center post. Although accidental separation is improbable this limits the potential for loss or damage to the bead.
