- 2027 New
tanakadaisuke is a collection brand led by Daisuke Tanaka, a costume designer and embroidery artist. Using beads, bijoux, and lace worked entirely by hand, his embroidered pieces carry a classical elegance while balancing femininity and sophistication — a duality that defines his singular creative world.
This techo cover, born from the first-ever collaboration between tanakadaisuke and the Hobonichi Techo, is a tri-fold design in lustrous black velvet, complete with a black satin ribbon bookmark.
The design was drawn from tanakadaisuke’s White Handkerchief Handbag, with a lace handkerchief motif worked into the flap. At the tip of the handkerchief motif sits “snow bijou,” a bead-embroidered lace piece inspired by falling snow — each one stitched entirely by hand. The flap fastens with a snap button.
The upper portion of the handkerchief is also adorned with delicate tanakadaisuke embroidery.
The pen hook on the inside is designed to hold a pen by its clip.
It comes with a drawstring bag printed with the tanakadaisuke logo to protect the delicate velvet and embroidered lace, allowing you to carry it safely and with care.
This cover is a graceful and luxurious companion that grows more cherished with every passing year of use.
