Metal up your head!
Metal Head 04 carries a galvanized steel tip with a built-in ball of 4 mm of diameter, which you could virtually write with almost on every surface, in all conditions. Try it on rust! The soft plastic of its body allows to squeeze it without any stress, in order to measure out the quantity of paint. Metal Head is easily refillable with the suitable Grog Refiller, it carries an antidrip rim for writing without getting dirty and it contains an extra-permanent concentrate of Full Metal Paint which is almost impossible to be removed, once it dries.

4 mm, ca. 50 ml paint.
