Ongrok Airtight Aluminium Storage Tube

The Ongrok Storage Tube is a pocket-sized aluminium tube with a double O-ring seal — two rings rather than one, so it stays airtight and water-resistant for far longer than a single-seal tube does. The cap is a friction fit that pops off with a thumb; the base unscrews entirely so the tube can be rinsed straight through.

Anodised aircraft-grade aluminium blocks light completely, which does as much for keeping contents in condition as the seal does. Three spare O-rings come in the box. Seven colours, matched to the rest of the Ongrok range.

How it performs

It holds a pre-roll or a session's worth of material, keeps odour in and rain out, and survives a pocket, a bag or a keyring without opening. The unscrewing base is the detail that makes it better than most tubes: residue collects at the bottom, and being able to take the bottom off means it actually gets clean.

Looking after it

Unscrew the base, soak, rinse through from both ends and let it dry before the O-rings go back under load. Swap an O-ring the moment it looks flattened — that's what the spares are for. See our cleaning products.
