We at HIGHTOP have developed the HIGHTOP ASH & STASH doob tube with an airtight and waterproof container to hide any unwanted odors, and to protect your cigars/pre-rolls from outside elements. What differentiates our HIGHTOP ASH & STASH is the incorporated patent pending ash & stash mechanism at the top of the tube. Which its main purpose is to scrape off all of the unwanted ash when saving for later. With a couple of twists, you can extinguish your cigar/pre-roll and stash it for later use with no lingering odors or ashy aftertaste.
