Our Verdict
If you are looking for a mug that forces a double-take at the breakfast table, the 450ml Butt Drinking Cup is certainly an unconventional choice. I spent a week putting this borosilicate glass piece through its paces, using it for everything from morning iced coffees to evening herbal teas to see if the design was as functional as it is cheeky.
Performance & Build Quality
Constructed from high-grade borosilicate glass, the mug feels surprisingly substantial and resistant to the thermal shock that often plagues thinner glassware. The build quality is impressive, with a smooth finish that handles both boiling water and dishwasher cycles without showing signs of wear or clouding. Its durable nature suggests it is built to survive more than just a few rounds of humor.
Day-to-Day Experience
Using this cup on a daily basis is surprisingly intuitive, as the ergonomic curves actually offer a unique grip that fits comfortably in the hand. Cleaning is straightforward thanks to the glass material, though the unique silhouette means it works best as a statement mug rather than a stackable kitchen staple. It quickly became my go-to for guests because it guarantees a reaction every single time.
This is the perfect gift for anyone with a quirky sense of humor who appreciates high-quality, functional glassware.
Final Thoughts
While the design is playful, the craftsmanship behind the 450ml Butt Drinking Cup is serious business. With a solid 4.89 rating and a fair $22.00 price tag, it is a fantastic addition to any collection for those who don't take their morning routine too seriously.
