Pack of 5 proTect drying capsules.
Used to keep moist sensitive filament, such as proCarbon, proNylon, and proGlass, dry while not in use. They absorb water and by so shifts colour from orange to green.
When moist (green) they can be dried and reused (returns to original colour). Used together with ZX403 proTect Vacuum Bags, 5 pcs.
