Do you love chalk but hate the feel and dust? That's exactly how we think too. After years of working with a supplier, we finally developed an exclusive perfect formula of Zero Dust™ Chalk, called ButterStix®. They work and feel a bit like pastels as they glide smoothly on most non-porous surfaces. Not limited to chalkboards, you can write on most non-porous surfaces: use on walls, plates, counters, etc. Great for labeling containers, beer & wine parties, and more! Your imagination is the only limit!
