TOYO-SASAKI USURAI STRAIGHT SIDED TUMBLER SET OF 6

“USURAI” was developed based on the concept of developing practical products that are thin, beautiful, and have high functionality.

“USURAI” has been developed and commercialized over a period of about eight months and it has three main unique features.

1. TOTAL THIN WALL PRODUCTS: By realizing an unprecedented 1.1 mm thick mouth with smooth cutting, the glass looks nice and delicate.
2. STRENGTH IMPROVEMENT:  By using an unprecedented technology called "Full Surface Ion Toughening“, the strength of the product has improved, making it more resistant to cracking and scratching. In addition, cleaning with a washing machine was allowed.
3. WEIGHT REDUCTION: Reduced weight by about 33% compared with conventional products, making handling relatively simple.
