Designed for 11mm chalk. The tip can be screwed in and holds the chalk really tight. I wanted a very slim and elegant design, with a texture that is nice to hold.

Printing is challenging, because it tends to get knocked over. Those stabilising flaps at the bottom help a lot, but a wide brim is still needed.

Now go and enjoy chalk free hands! Also, it protects the chalk quite well, for easy transportation in your trouser pockets :)
