Midori Design Phil MD Envelope Vertical A (20582006) 4902805205825 (5 sets)

Envelopes made of MD paper that is comfortable to write on
This is a vertical envelope from MD Paper Products, a simple product made in Japan that focuses on writing.
It retains the writing comfort of MD paper, but has a double layer structure that prevents it from folding and is difficult to see through.

Comes with adhesive tape. It's easy to seal, so it's also suitable for letters from your travels.
