What is the Zebra Mackee Extra Thick?

It is the biggest Mackee, for large lettering. Zebra describes a tip that works as a flat chisel and as a square edge, drawing 8.0 to 17.0 mm flat and 10.0 mm on the edge. It uses the same oil-based, quick-drying, water-resistant ink as the smaller Mackees, so it is a sign and box marker, not a pen.

What are the specs?

29.4 × 183.2 mm and 63.2 g. Zebra lists:

Item	Value
Line width	flat 8.0 to 17.0 mm; square edge 10.0 mm
Ink	alcohol-based oil dye, black
Size	29.4 mm diameter × 183.2 mm
Weight	63.2 g
Part number	MC-EB-450-RT
Price	550 yen with tax (about US$3.48)

What can it mark?

The ink is quick-drying and water-resistant and suits paper, cloth, wood, cardboard, glass, plastic, metal and vinyl, but not soft vinyl items such as inflatable rings. Zebra gives no dry time. With this much ink laid down at once, drying will take longer than with a fine pen, so allow extra time before stacking boxes.

How big is it next to the others?

About 2.5 times the weight of a Hi-Mackee. By our arithmetic from Zebra’s weights, 63.2 g is 2.5 times the 25.1 g of the Hi-Mackee and 7 times the Mackee Care’s 9.0 g. The chisel tip at 17 mm is nearly three times the Hi-Mackee’s 6.0 mm thick end. At 550 yen it also costs about three and a half times the 165-yen Hi-Mackee.

How does it compare with the rest of the line?
