WH Smiths used to sell chinagraphs. I used them as lot as a driving

Just don't leave them in the sun inside the car or the insides all
run out.

Pay no attention to that man behind the curtain.

Funnily enough I went to WH Smiths, couldn't find chinagraphs, nor
crayons, but did find a semi-permanent liquid chalk pen!

Chinagraph pencils are the answer but they are hard to find. I buy online.
