✨ Why You'll Love It
Ultralight & High Quality Titanium
Made from premium TA1 pure titanium — lightweight, never rusts, acid and alkali corrosion-resistant, scratch-resistant, and high temperature-resistant. Titanium is harmless to human health, non-reactive, and preserves the original flavor of food.
Double-Wall Anti-Scald Design
Double-wall construction (not vacuum) isolates heat as much as possible to prevent burning — very suitable for drinking hot coffee and hot tea. Note: Not insulated for temperature retention.
Stackable Space-Saving Storage
Four sizes (120ml, 200ml, 300ml, 400ml) nest together — small cups fit inside larger ones for convenient storage and space saving. Comes with a mesh bag for easy carrying.
Easy to Clean
Smooth surface reduces sediment adhesion, making the cleaning process much easier. Dishwasher safe for effortless maintenance.
Lids with Stand-Up Handles
Each cup comes with a lid — no sealing ring. The handle on the lid features a welded card slot, allowing the handle to stand up for easy pickup and placement.
Versatile Use
Ideal for outdoor camping, picnics, backpacking, hiking, travel, office use, car trips, and family picnics.
