I do a lot of whiteboarding and grew tired of juggling caps, especially while using multiple colors.. The clicker markers seem to run out of ink to fast so I made this as a solution!
It holds the standard EXPO dry erase markers and fits snugly keeping them air tight.. Let me know what you think and please send me any variations you come up with!
Comment on this post your results so we can dial in the best fit.. If you have any mods to fit this to other sized markers paste link in the comments. With that said, let me know how it works for you!
