These were purchased as a filler item and because highlighters are always in short supply. I check them for legs and have never seen them but these little guys sure walk away! The colors are bright and the odor is not enough to send me running for the headache meds like some highlighters.
I much prefer the color display (trueness brilliance) of the alternate 'Hype' pens. But my real preference is the Sanford uni-Blazer view pens that I used to purchase. However I cannot find them anymore.
