Those are two similar models, found once again in “30 boîtes en origami” (page 48 for the flower box, 52 for the spiral).

They are made with 8 sheets of square paper, 4 for the bottom and 4 for the lid.

The left spiral box is made from Daiso Fabric paper 15 cm. The right box is made from Daiso Yuzen chiyogami paper Vegetation 15 cm.

The left box is made with star paper found on eBay, the right box is made from music sheets cut to 15 cm, found on amazon.

Details of the lid.

The flower boxes are made from: left, Jong le Nara pattern colored paper flowers for the bottom, Daiso handmade paper Sukigami for the lid, both 15 cm ; right, MarpaJansen glassine paper 10 cm ; middle, Grimmhobby washi chiyogami 7.5 cm (the box is tiny, very cute :)).
