A customer testimonial highlights their remarkable resilience, with one glass surviving a drop onto granite, a bounce into a steel sink, and remaining intact. This durability is attributed to advanced protection, though breakage is always a possibility with glassware.

Know before you buy
Toyo-Sasaki uses a proprietary HS Platinum strengthening technology that increases the glass's resistance to physical impact and thermal shock. While no glass is unbreakable, this treatment makes them significantly more resilient than typical household tumblers.
Yes, the tumblers are specifically engineered with a tapered shape that allows them to nest neatly. They are designed to stack easily in kitchen cabinets without jamming or becoming difficult to pull apart.
These are single-wall glasses intended primarily for cold beverages like water, beer, or juice. While they are heat-treated for durability, they are not insulated and will become hot to the touch if filled with boiling liquids.
Yes, they are fully dishwasher safe. The Hard Strong technology is designed to withstand the rigors of commercial dishwashing environments, so they will hold up well in a standard home dishwasher.
Each glass holds 6.76 ounces, making them a perfect size for a standard water glass, a small beer, or a serving of juice. They are compact, standing at 3.125 inches tall.
