I think I found this in the recycling at an old shared studio space. It's a bit like a physical version of Slack. A method of sending internal messages and threads of information to colleagues. Perhaps with it being resealable and with the little holes in it's more of a public group than a private one.

I like the colour and utilitarian feel of the grid and type. A price of design that looks like it was intended as purely practical, but ended up looking ace.
