Yesterday, a small naval-themed shipment arrived from Litko. I've never ordered anything from them before, but they have an excellent section of naval accessories for the tabletop, so I got a few things as a test run.
Some small (as I'm using them for 1/2400) "burning" markers:
Is it just me or do they look like Marge Simpson's hair?
Some medium-sized "make smoke" markers, which would also be nice for "low-lying clouds":
Everything is acrylic and in 2-4 pieces, but very easily glued together. I'm extremely pleased with Litko's stuff and I'll definitely be ordering from them again (and again)!
