The Games Workshop produced Warhammer 40k Counter Set is a great idea – that doesn’t quite work as delivered.
The markers are bright translucent green (same material and color as a Necron Gauss rod) and completely unreadable from more than a foot away.
An easier way to keep track of your 40k army during the heat of battle:
After a quick shot of grey Krylon primer, a brush-full of Citadel Badab Black wash, a quick drag of light drybrush and 10 minutes of red detail work – they are now fun, usable markers that match my Space Marine faction colors!
