Know before you buy
HS stands for 'Hard-Strong,' referring to Toyo-Sasaki’s proprietary physical toughening process. This treatment specifically reinforces the rim of the glass, making it significantly more resistant to chips and breakage than standard soda-lime glass.
Yes, they are specifically engineered with a stackable profile. The shape allows them to nest securely, which helps prevent them from getting stuck or tipping over when stored in a cupboard.
While these tumblers are durable, they are designed primarily for cold drinks. We recommend avoiding extreme thermal shock, such as pouring boiling water directly into a cold glass, to maintain the integrity of the toughened material.
Because of their toughened rim and overall durability, they are sturdier than typical thin-walled glassware. However, they are still made of glass, so they should be handled with the same care you would give any high-quality drinkware.
With a 67mm diameter, they have a slim, ergonomic profile that is easy to grip. The 250ml capacity makes them a versatile size for water, juice, or cocktails.
The HS toughened glass is designed for commercial use, where it undergoes frequent high-temperature washing. It is highly resistant to clouding and maintains its clarity well, provided you use a standard dishwasher detergent.
