Staedtler Lumocolor Permanent Omnigraph Crayon – Blue (Box of 12)

Blue's the go-to when you need a clear, calm mark that still pops on a dark board or a transparent sheet. The Staedtler Lumocolor Omnigraph in blue lays down an opaque, waterproof line on paper, plastic, metal, glass, wood, leather and stone. No sliding off, no fading after a wipe, no bleed-through to the page underneath. 12 mm diameter means one confident stroke does the job.
