Uchiyama Tumbler Stainless Steel Vacuum Insulated Tumbler Cup Double Wall for Coffee Gift Camping, Black Made in Japan
This tumbler is made of two thin stainless steel materials stacked on top of each other, creating a space between them to shut down heat from the outside. This prevents heat dissipation and temperature changes due to heat transfer.
A special surface treatment called ion plating is used to improve the surface durability and wear resistance of the stainless steel material itself.
The shape of the tumbler is a gentle parabola, with the mouth opening outward slightly. When you hold it to your lips, you will feel that it is easy to drink.
One of the features and greatest strengths of LIFE UW FACTORY is that we do everything in-house, from welding the raw material stainless steel to polishing it. In each process, skilled craftsmen take charge of manufacturing and pass the baton to the next process.
