The "Nervion Rockstar" tumbler, brought to you by Caterboss, is more than just your average glass. Crafted with the highest quality, this fully tempered tumbler is designed to handle the hustle and bustle of hotels, bars and restaurants. One of the prime features of these tumblers is their durability. They possess an impressive level of consistency and quality in the glass clarity. Constructed from rim to foot, these pieces are tempered to resist mechanical shocks, extending their lifespan up to five times compared to non-tempered glass ranges. A standout feature is the beaded rim, which reinforces the strength on the glass's vulnerable edges. This design minimises chipping and significantly extends the tumbler's lifespan. With a resistance to heat up to 135C, these tumblers have been thermal shock tested and can withstand changes in temperature from hot to cold without a hitch. What sets the Nervion Rockstar apart is its safety features. Should a mishap occur and a glass break due to an excessive blow, the tempered glass will shatter into small pieces, making it safer than non-tempered glass. This is particularly important in the hospitality industry, where safety is paramount. Moreover, these tumblers are dishwasher safe. They're strong, durable, shock-tested, and can endure the rigour of industrial dishwasher cycles, all while maintaining their pristine clarity. The stackable design of these tumblers is a cherry on top. Not only do they save space, but they also help maintain order and provide extra work space in busy establishments. Caterboss's Nervion Rockstar tumbler is no ordinary glass, it's a game changer. With its durability, heat resistance, safety, and practical design, it's ready to elevate your establishment's hospitality experience.
