We like sets like these, but they can be hard to describe.  First, you might know that BTS is a world-famous Korean boy band.  As for this set, the cardboard cover (still sealed in its original shrink wrap) says there are 30 postcards, 30 bookmarks, and 280 “pasters”, which we interpret as stickers, though this type of set sometimes gets the number of stickers wrong.  The reverse cardboard cover shows thumbnail photos of much of all this.  Sourced in China, it’s a set likely to please fans of this popular band.  Grade: 1
