20 oz vacuum-insulated stainless steel tumbler with a glossy exterior, clear push-on lid and rubber gasket. Built for all-day temperature control and everyday knocks — a solid choice for commuters, desks, and on-the-go routines.

The tumbler’s double-wall vacuum core keeps hot drinks hot and cold drinks cold longer than a single-walled cup. Stainless steel resists staining and rust, while the glossy finish makes it easy to wipe clean and gives a polished look on the go.

The clear lid snaps into place and uses a rubber gasket for a dependable seal (not leak-proof if tipped, but very good sitting upright). Rounded edges make the body comfortable to hold; the slimmer lower diameter slips into most cup holders but still feels substantial in hand.

  • Construction: vacuum-insulated, double-wall stainless steel for effective temperature retention.
  • Capacity: 20 oz (≈0.59 L) — room for a generous coffee or a tall iced drink.
  • Lid: clear push-on lid with a rubber gasket for a snug fit and reduced spills while upright.
  • Finish: glossy exterior that cleans easily and shows color well for wraparound prints.
  • Practicality: durable, corrosion-resistant, and suited to daily carrying and travel.

This tumbler is made for real life: commuting, desk days, long errands, and outdoor breaks. Its insulation keeps your drink closer to the temperature you poured in, so it’s handy for slow sippers and long meetings alike.

  1. Commute ready: fits many car cup holders and keeps drinks at serving temperature during travel.
  2. Daily desk cup: reduces trips to the kettle and keeps cold drinks chilled through the afternoon.
  3. Outdoor use: sturdy for picnics, hikes, and casual outdoor work — rinse and reuse without fuss.

Quick tip: if you want a quieter lid, remove the gasket and rinse it separately — it will snap back on without tools.

Dishwasher-safe for convenience, though hand-washing the lid and gasket will keep seals fresh longer. Remove the rubber gasket occasionally to clean the channel — trapped moisture is the usual cause of lingering odors.

Avoid bleach, oven use, and the microwave. If you hand-wash, use warm water, mild soap, and a soft sponge; dry fully before storing to prevent trapped moisture. Replacing the gasket after a long period of heavy use helps maintain a tight seal.
