How big are the Flags?
The country flag stickers are 66mm wide and 51mm Tall and the country flag inside the sticker, just in case you want to cut it out to make it smaller, is 60mm wide by 35 tall.
So for the Bikers out there you can cut them to have no names and stick them to your valuable pannier space. A sharp knife is recommended! They are pretty much the ideal size for helmets and panniers. If must be said the adhesive is NOT approved for helmets BUT if you check with your helmet manufacturer you might find the adhesive will not affect them. The adhesive is a Solvent Based Acrylic. The High Tack versions are designed to stick to plastic so I cannot imagine (no warranty applied here) that it will be terminally bad. Terminal being the operative word!
I've added the sizes to the FAQ.
