It was many years ago, but I think it was a prize you'd get one for every purchase at Lawson. There are 20 in total. A bonus mini letter set is included. All are in their outer bags. New and unused. The photo is a little hard to see, but the Lawson logo is on the back. Please note that we do not sell individual items. Due to moving, we cannot accept returns. If purchased by evening, we will ship the same day. Thank you for looking.
