The Union Jack flag of the UK seems to have had a bit of a resurgence of late in the world of design, very cool Britannia!
This listing is for a traditional Union Jack design stamp. It looks great inked up in the flag's usual blue and red (I used dauber duos ink pads here but you can use stamping pens to ink in detail). It also looks just as recognisable inked up in the one colour.
The stamped image measures approx. 3.5cm x 2.5cm (or 1 3/8” x 1”).
