BTS, one of the most notable K-pop boy groups, is working on another collaboration with global fast-food chain McDonald’s. This would be their second venture after the release of BTS meal in May.

This time, the members are directly involved with McDonald’s in the process of creating Saucy Collection and Melting Collection. Saucy Collection consists of the global Louis Vuitton ambassadors’ hand-drawn characters, in which their mouths are drawn using red sauce along with their hand-written scribbles. Meanwhile, Melting Collection is a pop-art merch mixing the artworks of the group’s latest song, Butter, and McDonald’s objects.

The collectible items range from pajamas, t-shirts, cushions to keyrings. The merchandise went on sale starting June 17 via Korean shopping app Weverse.
