These are so useful! A very simple design that is genius. This is one of those products that make you think wow! Why hasn't anyone thought of this before? So easy to use and a great way to make sure you don't spill coffee all over your work. A desk isn't always a fantastic place to put your drink, especially if you tend to be clumsy. The Coffee Cup Desk Clip solves this problem. A very innovative and inexpensive solution to an everyday problem. Not just for the office either. You can attach these to any flat surface. Dining tables, picnic tables, or anywhere else it will fit. Great for fishermen who fish from piers or jetty's where there are rails. Or for dining when you have limited table space. You could clip one onto a child's desk to hold paint or glue. So many applications, the list is endless!
