Threw these in my cart on a whim, but they turned out to be so useful! It's basically a giant crayon, designed for marking lumber. But you can write on a huge variety of surfaces, making these awesome to have in the workshop or around the home.

Writes on everything!

Great to write in tires!!

It's a grease pencil, great for labels on car tires

These write on a huge range of surfaces, very nice to have in the garage or around the home.

Excellent
