Our company was established in 1997, is a professional exporter of high borosilicate glass products .
Unique shape design and using high borosilicate glass as raw material.
These glasses are perfect for serving everything from beer, cider, whiskey, champagne, juice and cocktails, to coffee, tea and hot cocoa.
We had testers evaluate each glass’s visual appeal and if their size and shape made them comfortable to hold and drink from.
We dropped strengthened glassware onto hardwood and marble surfaces from a height of 3 feet to compare their durability.
We scraped the colored cups with a razor blade to be sure the coloring was inherent in the glass and not a coating that could be scratched off.
We checked to see if stackable glasses stuck together and if they could be easily pried apart.
