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 Striped 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.
