Can I use these on fabric and have it stay on the fabric after wash?

Hi, thanks for your message. The company that produces the product unfortunately doesn’t have informations about fabric. They just say that the product is for paper. Regards.

What is the sizes of the fine tip as I don't see if listed anywhere?

The package says 0.5-0.8 mm for the fine tip. The brush tip is 1.0-6.0 mm.

Are these the same as mars duo and if so what’s the diffferrnce
