Thank you for your question.
Kawanishi Kaban's canvas series is made using a canvas material called "18oz paraffin-treated army duck."

The relationship between size and ounces is as shown below, so the "18oz Paraffin-Processed Army Duck" used in Kawanishi Kaban's canvas series can be said to be a fabric that is somewhere between No. 6 and No. 7 canvas.

Size g/m2 g/sq yd Ounce (oz)
No. 5 canvas 720 602 21.3
No.6 canvas 647 541 19.1
No. 7 canvas 573 479 16.9
No.8 canvas 500 418 14.8



By the way, the reason why we use this "18oz paraffin-treated army duck" to make our bags is,
This material has a high density, making it very finely woven and giving it an elegant look.

Durability is important, but we believe that elegance also brings joy to those who use it.

Thank you for asking.
