On March 14, 2025, I experienced a frustrating incident.When I was keeping track of my expenses on the whiteboard, I accidentally lost the cap of my marker. Fortunately, I had already launched the CAD software on my laptop, so I quickly made a cap that matched my marker!

The pen caps fit the markers perfectly, just like the original pen caps, and you can print them in various colors. I like to print them in white to match the base color of the markers.I hope this is helpful to you. Here's a small printout!
