Says "visual clues to ink color and tip type" - yeah since they are black you could infer the ink is black. and there is a chisel graphic - but it looks more like a flag. Saying barrel type is "tank" is misleading - it is simply SQUARE instead of ROUND so it won't roll off your desk. Don't assume it is an ink tank because IT IS NOT. We had thought "tank type" markers had a liquid reservoir but they have the standard ink soaked fake felt in the barrel. They still last a tad longer than Sharpies but that may be due to the chisel tip being noticeably smaller so you use less ink when writing out labels and CANNOT write as bold as with a Sharpie chisel point marker.
