It is a cup look like a lens. The creative cup design is a 1:1 simulation to the Canon EF 24 -105mmf/ 4.0LUSM lens. 99.9% similar to the original Canon 24 -105mmf/ 4 Llens. Made of food grade PVC plastic materials, safe to use for drinking. Volume of liquid hold is around 375ml. So you can use it to drink coffee, milk, water, fruit juice, ice-cream, and etc, as you can imagine. It's a model cup, and not an actual lens. Best collection for Canon fans. An amazing gift for your friends, classmate, colleagues, friends, relations on holidays.
