Birdie Paper Knife Brand: h-concept This is the Birdie paper knife designed by Yohei Oki. The body is made of polybutylene terephthalate (PBT), a synthetic resin with a firm hardness. The matte surface has a high-quality texture, and it can open letters efficiently without bending. You can quickly open letters from loved ones, as well as a batch of envelopes for office use. The curved back, which is the motif of a bird, is designed to be held firmly with one hand without requiring unnecessary force, allowing for easy opening. Of course, when not in use, it has a design that allows it to gently sway on your desk, making it a great interior decoration!
