These highball glasses feature an attractive fluted pattern at the base of each glass, bringing a shimmer and sparkle to every sip and pour. They're part of Toyo-Sasaki's Hard Strong Platinum Technology collection, which means they're made with premium-grade glass that's both durable and dishwasher safe.

Testimony by an Umami Mart customer:

“I dropped a Hard Strong glass on my granite counter top, then it bounced into my steel sink and nothing happened! I saw it with my own eyes in slow motion, sure it was going to shatter during the tumble. These are truly Hard Strong!”

*This testimonial was given in March 2014, in regards to the Fluted Double Rocks glass, which has the HS Platinum grade protection. Glassware breakage is inevitable but the extra HS coating (plus good care and a little luck) helps to prevent it when possible. Read more about the Hard Strong technology here.
