Frequently Asked Questions
Are Keep Smiling markers waterproof?
The gel ink resists moisture once it fully dries on the surface. This prevents the pigment from bleeding if the material gets wet.
Can Keep Smiling pens write on glass?
These pens adhere to non-porous surfaces like glass and polished metal. The metallic base remains opaque without scraping off during handling.
