Kaku 6 Envelope, Burgundy, 114 Sheets

Kaku 6 Size (162 x 229mm) Japanese Envelope, Kaku Type
Kaku 6 envelopes, also known as Kaku 6-go, are non-standard size envelopes that perfectly fit A5 size paper (A4 folded in half) without folding. They are just the right size for including paperback books, planners, and 2L photos. They are slightly smaller than the commonly used Kaku 5 envelopes and are recommended for enclosing items that are not too thick.
