The Tenth United States Army, often abbreviated as the 10th US Army, is a field army of the United States Army. Established during World War II, it served primarily in the Pacific Theater under the command of General Douglas MacArthur. Originally formed for the invasion of Japan, the war's end rendered this operation unnecessary. Instead, the 10th US Army was deployed to occupy and administer post-war Japan until its dissolution in 1952 when the United States Military Government in Japan ended. The Tenth US Army was unique in that it comprised troops from various branches of the U.S. military, including the Army, Navy, Marines, and Air Force, all coordinated under one command structure. This interservice cooperation proved beneficial during the post-war occupation, where the army played a significant role in rebuilding Japan's infrastructure, establishing democratic institutions, and overseeing the demilitarization of the country. After its dissolution in 1952, the Tenth US Army was officially redesignated as the US Army, Far East Command (FECOM), which continued to serve U.S. interests in Japan until it was further reorganized and renamed as the United States Army Japan (USARJ) in 1973. The modern-day USARJ continues to play a vital role in maintaining strong military relationships with Japan, supporting peacekeeping missions, and providing humanitarian aid throughout Asia.

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.

One size: 20 oz (≈0.59 L). Dimensions below help with shelf placement, cup-holder fit checks, and packaging decisions.
