These glassware sets are a take on the classic vintage mixed pack, updated with my own nature & scenic inspired silhouette art. Updated by being Dishwasher & Microwave Safe, they are also replaceable, & with ever expanding options to add to your collection, are easy to combine with other sets. What started as a question "Do you ever draw whales?" Became my latest drawing & design series! Humpback, Beluga, Narwhal & Sperm Whale are my top 4 favorite whales, I love having them as my new glassware set! They also coordinate perfectly with the rest of the Collins glass collection. Original Art on printed Commercial Grade & Dishwasher safe on high quality glassware. 15oz ARC Aristocrat Cooler Glass. Highest standard glass material. Clear tall cylindrical shaped beverage glass. Made in the U.S.A. Packaged in reusable & recyclable cardboard boxes.
