The Strikers are the brand new Ironlak technical drawing pens and sketch markers. These markers are very high quality with alcohol base inks and nibs produced in Japan. Strikers sketch markers are twin tipped with a medium broad chisel and fine tip. There are 5 sets with 20 mixed and different colors in each set, and no overlapping. Every sketch set comes in its own canvas carrying case that can be set to stand up for easy viewing.
The set #1 doesn't contain a black marker anymore. If you need the black Strikers marker, you can find it here
The markers are in very good condition and the range of colours is fantastic. My only complaints are that the cases are often so tight on the markers that it's difficult to get the markers out without it catching on the lid of the marker and pulling the lid off before getting the marker out. The markers do bleed quite a bit on the page, but this is something I expected, and it'll just take a little while to become used to...
