Sewline Lead Refill White,

I put these in a 0.9 mechanical pencil and use them for marking cut lines on dark wood for woodworking. They work great!

These markers are awesome! I have purchased these several times. The colors show up excellently on dark fabrics...all except the yellow.

It's a great very fine line to mark on dark fabrics.

I wanted a pencil for marking on darker woods and decided to give this a go. I picked up an inexpensive Pentel mechanical pencil and popped in this "lead." It marks well and comes off the wood easily. It's soft enough that it doesn't damage the wood fibers at all. So far I've used it on rosewood and padauk, it worked very well.

I love this chalk pencil for tracing. I favorite of all I have tried.

The best pencil for marking dark fabric I’ve found

This lead is great for marking & making accurate cuts on fabric. It's also very easy to remove from fabric.

Purchased because Fons & Porter was unavailable. I must say I am extremely surprised and more than satisfied with this marking lead for marking seams on my quilt pieces. It is slightly harder than Fons & Porter resulting in a finer line which I find preferable. The lead fits the Fons & Porter mechanical pencil perfectly. I will definitely purchase again and will indeed recommend to my fellow quilters. I also purchased the pink, blue, and green leads but have neither used nor written a review for those colors. I can't imagine they would not measure up to the quality of the white lead.

Mi trabajo requiere medidas precisas y con la ayuda de estas puntillas (minas) puedo estar seguro que las distancias se marcan donde yo las necesito.No es necesario comprar un lapicero de la misma marca pero sí uno que pueda manejar puntillas de medida 0.9mm.Una de mis principales preocupaciones es que se gastaría muy rápido pero afortunadamente tiene una buena durabilidad.
