After having another brand of reusable cup spill coffee into my backpack I was on the search for a spill proof cup. The other reviews do not lie! Have shake tested the cups and there's no spills! Bonus that they're very stylish and fit under a standard group head for pulling shots directly into them.

The best spill proof cup, throw it in your bag and don’t worry about anything <3

Received a Fressko Bino Reusable Cup as a gift and later purchased two more for friends. The sleek design and quality materials make it not only stylish but also durable. I love how the cup can hold both hot and cold drinks. The spill-proof lid is a godsend! Highly recommend these cups to coffee lovers!"
