Every piece is printed to order, in France. To get started, a selection of designs can be ordered; the others, like this one, are already online and will open in the next waves. No made-up stock-out: there is no stock, there is a queue.

## Translation for humans
The “clearfix” is a CSS trick from another era, when page elements were set side by side by making them “float” and their container had to be forced to hold them. This one dates from 2009, says “do not touch,” and nobody knows what it's holding up. Like that box at the back of the closet: you don't open it, you just move house with it.
**Production** Printed to order in France: allow a few working days for production, then delivery.
**Shipping** €4.90 in France, free from €59.
