Keep it long, treasure it long.

Functional beauty and lightness

TSUTSU's Hairline food carrier is made in Tsubame City, Niigata Prefecture, a town known for metalworking.The sharp and delicate appearance that makes the most of the original texture of stainless steel is appealing.The fine surface, which looks as if it has been scooped up from the surface of a river, has been polished by craftsmen one by one.The warmth of human handiwork can be felt in the inorganic impression of stainless steel.

Simplicity to the extreme

The first thing that catches the eye about TSUTSU food carriers is their smooth surface.The stainless steel is made as thin as possible by machine processing, and then polished by hand one by one by craftsmen to create a beautiful hairline finish.The smooth finish, so smooth that you cannot tell the seams are there, is the result of craftsmen's hands and ears that discern accuracy of 1/100 mm.Even with the advancement of technology, nothing can compare to the flexibility and precision of the human hand and eye.In addition, the finished product undergoes more than 70 processes, from manufacturing to inspection, paying attention to even the most minute irregularities that cannot be seen by the naked eye.Furthermore, while sampling inspections are the norm for finished products, all products are subjected to performance tests twice before shipping, which shows the strong commitment to quality by the manufacturer.The heat-retaining and cold-retaining effects of food carriers are created by a vacuum layer inside the container that keeps the temperature of the drink. TSUTSU is designed with a triple layer of metal containing aluminum, which has excellent heat-retaining effects, and a vacuum layer to further enhance the heat-retaining and cold-retaining properties.Furthermore, the thicker the metal, the more heat it absorbs, so TSUTSU suppresses heat absorption and dissipation by making the inner stainless steel as thin as possible, at 0.1 mm or less.This not only maintains the drinking temperature when on the go, but also makes it light enough to be easily carried around.In addition to keeping hot soup hot, this food carrier also keeps it cold, making it convenient for holding fresh salads, fruits, and other cold desserts.Although slim, it holds about 4 ladlefuls and can carry plenty of food.The simple shape of the lid and body, which could not be further reduced, leaves only the elements necessary for function, and the easy corner-to-corner washing is perfect for busy professionals and those with families.The minimal parts and thin construction are both surprisingly light and durable, making it ideal for daily carry.The material characteristics of stainless steel, which is clean and resistant to adherence of ingredients and colors, is another key to its long-lasting use.It is a great gift for yourself or family members, as well as for birthday gifts, job hunting gifts, etc.

Skillful Stainless Steel Processing

The origins of metalworking in Tsubame-Sanjo can be traced back to the Edo period.The manufacturing of Japanese nails, which began as a side job for farmers to overcome the flooding of the Shinano River, eventually developed into farming tools, kitchen knives, copperware, and stainless steel products, and the industry has expanded with the times.Today, Tsubame-Sanjo is known as a town of metalworking, with a wide range of metalworking operations ranging from the manufacture of machinery and automobile parts to Western tableware.Founded in 1965 in Tsubame-Sanjo, the TSUTSU brand was developed by SUS Co.The company began by manufacturing metalware using the "spatula drawing" technique by skilled craftsmen. In 1983, the company began manufacturing and selling stainless steel vacuum flasks developed in-house, and the TSUTSU bottles were completed by combining the stainless steel vacuum flask manufacturing technologies accumulated over the years since then.While many companies have moved the manufacture of vacuum flasks and bottles overseas, TSUTSU is a manufacturer that continues to manufacture high quality products with a focus on Japanese products.
