so, what kind of chalk refills? i have this handy-dandy (chalk pencil) refillable, the chalk is about 1/8th inch thick, shaped like a long pencil lead, takes different colors of chalk...i don't know what i would do with out it, i use it every single day! or is is fat chalk? chalk is good for most of my marking tasks, the chalk brushes off, does not leave marks,
if you really have no use for the 'gift' post a picture of it...someone will know exactly what to do with it and put it to good use, you could (re-gift) it at some point...or find a good use for it after all and put it to use, or just pass it on if it's just not something you will use...lots of places to donate too...like school art department.
