Replying to @Myimani This is a valid concern! I had the same concern when i decided to add glasses to my shop to be able to offer cute items at a lower pricepoint. I did extensive research and ultimately chose libbey brand glassware as well as my manufacturer for my sublimation glasses. All vinyl and sublimation glasses in my shop can withstand hot to cold temperature changes and can be used to make espresso as well as hot tea. Youd have to chuck one pretty hard to shatter it #glassware #libbey
