It’s always useful to have a cup handy, but hard to find room to carry one where it’s easy to get to in a tank bag or jacket pocket. Regular cups are too bulky and cylindrical. Cheap, unreliable and fragile plastic versions of this telescoping invention have been around forever...but beautifully crafted, durable stainless steel ones like these are rare. Packs neatly anywhere so it’s always at-the-ready. Suitable for enjoying hot or cold beverages. About 1"×3.5" (folded). Quaff away.
