Pilot jumbo marker
$3.50
Pilot Jumbo Permanent markers have large chiseled nibs, and are filled with ultra permanent Pilot brand ink. One really nice feature about these is that they are easily refillable with Pilot Ink and the nibs are built so well that these markers last. The 10mm nib is built tough and can write on more surfaces than most markers. Pilot Jumbo markers also have a large ink capacity so you don't have to refill them as often.
