This pencil from Sewline comes with white, black/gray, and pink 0.9 mm chalks. It is handy to have three colors in one pencil especially if you have limited space in your traveling sewing kit.
The pencil comes loaded with one lead in each color. I don't use the pink chalk so I replaced the pink with white. It's not obvious how to refill this pencil but luckily, there's a video!
