///AN ITEM THAT CANNOT BE FOUND CANNOT BE TAKEN™ | HOME | GALLERY | REVIEW | AUTHORISED STOCKIST ///ABOUT Designed in 2006 by OscarDelta SPD Go-Tubes are the ultimate deep carry concealment device for small items that you would like to protect from damage, loss, or unauthorised access. The tough but lightweight construction protects the contents from being crushed or ruined by liquids, though its primary function as a security device is delivered through concealed use. Go-Tubes are used to secure sensitive and valuable items by relocating them from the usual storage locations; to a safer, hidden location. Quite simply, an item that cannot be found, cannot be taken. Ideal for emergency money (will take 10 x $100 USD), mini flash drives, maps, documents, geocache, glow sticks, matches, sewing kit, spare batteries (2 x AA or 4 x CR123) and other small items. Simple Design Lightweight 22g Airtight Waterproof/Mildew-Proof/Sand and Dust-Proof Silent Operation 100% non-metallic External Diameter 20mm Internal Diameter 16mm (5/8 inch)
