You will need some type of funnel ( we made one out of paper) to get this powder into your chalk liners Also, as far as I know, this stuff is hard to get off if you accidentally apply it to the wrong area of fabric.

difficilement effaçable en couture pourquoi ?

Ottimo ricambio

I bought the whole pen in 1 color and whow!!! I had no idea this was out there. As an upholsterer I used to labor w/ lousy school chalk which gets dull, breaks, etc. I am a professional interior and fashion designer w/ my own studio. I love this stuff!!!!!! I have it in various colors and use it constantly!

Fantastic, just what I needed to refill my chaco pen.There was a small amount of spillage and the end could be more tapered for squeezing the chalk into the pens more easily, but it's so much cheaper refilling as opposed to replacing that it doesn't really matter.
