I just received the current Enco Hot Deals flyer.  They have Dykem 
industrial markers, in nine different colors, on sale for $2.54 each. 

www.use-enco.com   Part # RV619-2909 will get you to the listing for the 
black color.   Or browse online Hot Deals Catalog page 77.

Usual disclaimers, no affiliation, California mileage may vary, etc...
