I’ve never used a chalk line before so I wish there was information on the package or online about how to use it. On the packaging there is a table about different colors of chalk, which I don’t understand, and a note to wear safety glass, which makes no sense, but no useful information. How do I load chalk into it? It doesn’t say.
I bought this non-prefilled thinking it was a better deal and came with more chalk. In retro spec this is something I use infrequently and the more chalk reason for purchase was dumb. I filled it not wanting to over fill it and on long lines some of the cord has no chalk at all on it. So, in my opinion for a weekend warrior buy a pre filled version and snap line away!!
