A mirror with a hole. Very minimalist. How big?

The A4 format (often also called DIN A4) is the most common format for writing paper worldwide and one of the formats standardized in the DIN standard "DIN 476" and the ISO standard "DIN EN SO 216".

A4 is 210 mm x 297 mm.

(DIN A5 is 148 mm x 210 mm and currently on SALE)

A nail is included with the mirrors.
A lot of text for such a reduced item.
