Articles quality.The size of 2 large stickers is a good size without sounding of a billboard that would ring true. Appearance deterrent, I think (but I'm not a burglar ...).
The size of two large stickers should be, about 7/8 cm long and 4 cm wide. The three small, about 3 cm long and 2 wide.
One good thing for the seller: the item ordered on August 28 was delivered the same day, an envelope!
