Black is beautiful,
Verified Purchase(What is this?)
This review is from: Staedtler Lumocolor Permanent Pen 318-9 Fine 0.6mm Line - Black (Pack of 10) (Office Product)
My principal use for these is for writing on plastic lables for garden/greenhouse use. The ink attaches well to plastic and dries almost at once and has retained its colour for a season without fading. The pack of 10 is far better value then buying them singly at a local stationers, assuming that they are in stock. I keep one at each of the various places where I might use them, far easier then having just one and carrying it around and losing it.
