"Hello, he also writes on glass and then holds that too? mfg"
A
"Hello. Yes, the edding 950 also writes on glass. It's a paste marker (a little waxy or comparable to a glue stick).
After drying it is wipe and waterproof according to the manufacturer and is suitable for marking glass. Paste markers are mostly used for dirty or coarse surfaces (rusty metal, stone, wood, ...).
Permanent and paint markers can also be used on glass. The question of adhesion to glass, however, depends more on the stress on the marked area."
