Emporion Crafts Hand-Blown Drinking GlassesRustic Bubble Glass Drinking Glassware from Mexico!We pride ourselves on the fact that all our Mexican Glassware is 100% Hand-Crafted & Artisanal. These glasses are all crafted individually, and as a result there will be a few differences between them in terms of bubble patterns and texture, but this is what distinguishes each one of them as a unique artisanal product which was created with care and attention.ENJOY the AUTHENTIC ARTISAN TECHNIQUEMexico is notorious for its top-notch artisanal craftsmanship. These MASTER GLASS-BLOWERS are able to greatly enhance their craft by incorporating their own traditional expertise to the well-known glass blowing techniques brought over from Europe around 400 years ago. Their ICONIC DESIGNS traditionally feature small air pockets mixed in with the glass at the creation process, which give all of their creations a beautiful look and stunning feel.DISHWASHER SAFETY & CAREFor best maintenance, hand washing these glasses is always recommended. They are also Dishwasher Safe, but since the tiny air bubbles traditional to these glasses may expand and crack when exposed to extreme temperature changes, please make sure to use the TOP RACK ONLY and allow the glasses a time period to cool off before removing them from the dishwasher. Not recommended for hot drinks nor for use in Microwaves.CARING FOR THE ENVIRONMENTIt is very important for us to protect the planet that we live in. We make sure to only use RECYCLED glass in our products in order to take care of the environment as best we can. Additionally, all of our Mexican Glassware is 100% lead-free!
