ATINY, carry your everyday essentials with a little Rock The Stage attitude. The ATEEZ MIGHTEEZ x COLLER String Bag combines a dark checkerboard pattern, contrasting star details and a drawstring backpack shape. It is a wearable accessory from the official MIGHTEEZ pop-up collection, ready to pair with your favorite casual outfit.

The official images show a clear front zip pocket beside a mesh pocket, a gathered drawstring top and cord shoulder straps. A MIGHTEEZ graphic label appears on the reverse. Use the visible pocket to add your own collection details, keeping delicate paper collectibles in suitable protective sleeves rather than placing them loose against other items.

Our supplier identifies this item as Lights On POP UP — STRING BAG; the official store calls it MIGHTEEZ x COLLER Rock The Stage String Bag. These names identify the same collection item. This is the full-size bag, separate from the smaller String Pouch sold elsewhere in the range.

Included

• 1 × MIGHTEEZ x COLLER Rock The Stage String Bag — one shared design.

Photocards, plush charms, bottles and other accessories pictured for styling are not included. No additional preorder benefit or supplier event gift is confirmed for this listing.
