Surprising!
Totally not what I had been expecting, but a completely happy accident anyway! (and that's my own fault for not reading) I got these thinking they were fine-tipped white markers. They're not. They're actually chalk, but in a liquidy soft format that makes it easy to use on paper (and photographs as evidenced in the LO I finally used them on). Think a crayon for your chalkboard. You don't get the chalky residue like you would when writing with regular chalk. These are fluid with good pigment and I'm really glad I got them! (Tho I still have to go back and get an actual white pen now!)
Will definitely be looking for other colors for these!
