Hmm, interesting question. I'm Danish but I don't actually know a word for it =D. In German it's called "Wachsmalstift", however =)

"zsírkréta", literally "grease chalk" (Hungarian)

Kredka pastelowa :D

Пастель (Ukrainian)

Giz de cera in Portuguese.

In French, it can be called "crayon de cire", which means "wax pencil". Indeed, the French word "crayon" actually means "pencil" in English. This is known as a false friend, of which there are many between English and French.

Krayon XD (loanword)

Thanks for the chance ^^

In Spanish it can be called "Lápiz de cera" (Wax pencil) or simply "Cera" (Wax), although most people call them Plastidecor, which is the most famous brand of crayons.

クレヨン in Japanese :)

Pastelka / Voskovka - Slovak

Thank you

Wow, didn't believed in that. Desired game.
Well, in Russian like in Ukrainian or other Slavic language, Pastel' (color pencil). I'm pretty far from art
