Lihit Lab - Envelope Case A5 - Clear (F-7744-1)

This case is thin, but can fit a nice amount of things in it. I currently use it to store two A5 paper pads, a couple envelopes, as well as loose postage stamps. It makes for a neat and tidy minimalist letter writing companion, easy to grab and take with me to various locations alongside a pen and some sticker sheets.
