Once again, this box is by Tomoko Fusè. It can be found in a japanese book, ISBN 4480872035, page 8.

It is folded from one sheet of A4 double-sided cardstock (150g/m²) by Maildor.

Nested inside are two masu boxes in 15cm flowery paper from Kyowa, and I just layed sheets of 5 cm crane folding paper from Jong Ie Nara on the masu’s bottom. It’s a bit much, but the colors fit perfectly together – it’s a precious little treasures box :)
