Pilot Jumbo Permanent markers have large chiselled 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

The Pilot SCA-6600 Super Colour Jumbo Permanent Marker is perfect for big and tough marking jobs

Super sized industrial marker has a chisel nib, giving it a 3.0 mm nib at its finest and 12.5 mm nib at its thickest
