We have been searching for a suitable plastic marker substitute because WOW do we (humans) throw "away" a stunning amount of markers (many hundreds of millions per year).
And what for? What really justifies the use of a marker that will inevitably dry out and then exist on the planet longer than we can fathom? Kid's drawings? Poster Projects??
We recommend using the China Marker Wax Peel versions for school, and for bright, vibrant color that just glides onto the page with no smearing, we recommend (when possible) splurging for a set of these Caran D'Ache Wax Pastels to keep at home.
WE KNOW they're not inexpensive - we know.
