I love this cup/straw combo so much, I use it every day. It was a bit of a impulse buy and it was off an Insta-ad so I was a bit nervous but I don't regret it at all.
The cup itself is glass with a plastic screwable top and the straw is a sturdy metal. I use it for literally everything from iced coffee to soda to water and i really like the shape of it. It's a lot more aesthetically pleasing than a regular mason jar and holds a fair amount of liquid too
The customer service team are stars too. I had a little issue with Canada Post but they took care of it and I had my package in hand a couple of days after. They were professional, kind and very helpful! 5/5 recommend this company and product based on this experience.
