Soft Matte and High Gloss sticker rolls can be written on smoothly with a permanent marker and some drying time is required to avoid smudging. Ball point pens also work (even on printed areas), but is not recommended. Natural Uncoated can be written on with most pens and markers.
As there are many types of pens, we highly recommended testing our stickers before purchasing to ensure it is suitable for your needs. Order a Stickers sample pack here!
