Description
I have questions with respect to:
1) Is the Line Friends BT21 Merch official or unofficial?
A: Majority of the BT21 merch is fan made (unofficial). There's a few official items for sale and the official items will say wording that's it's official in the product page. The more expensive items are official while the less expensive ones are fanmade. Unofficial BT21 will be much less than the price of the official version.
2) Are the photocards for sale official or fanmade?
A: Almost all the photocard sets for sale are fanmade or unofficial. If they are in the Under $15 collection, they are unofficial. If they are from a Lucky Draw or a album Pre-Order Benefit then they are 100% official and essentially come one by one unless you order a set via a Lucky Draw.
1) How soon will my item(s) will ship?
A: If we process the charges to your credit card, it will ship within 8 business days from the date of your order. The tracking information will get sent out automatically to the e-mail address you provided when checking out. If you do not receive tracking information from us within 8 business days of your order, feel free to follow up with us at support@kpop.exchange. Please be aware Pre-Orders will not ship until they are release and ship to us from Korea. The release date may be found on the product page.
2) How long are shipping times?
A: Your products will ship within 5 to 8 days of you placing your order then take 4 to 6 weeks to reach your doorstep. Each product at Kpop Exchange has an estimated delivery time that you can find in the product page.
3) Do you ship to PO Boxes?
A: Yes!
4) What's the ETA to USA and Canada?
A: 3-5 weeks is the ETA. On occasions it may arrive faster and during busy shipping times it may turn into 6 weeks. for items such as Albums and Official Merchandise, it's already in the US and is received much faster. The shipping speed can be chosen at checkout depending on fast you want to receive it.
5) Where can I find my tracking information?
A: The tracking will update on the order status page once the item is in transit. You will also receive an email notification with a link to your personal tracking page through my shipping program, AfterShip.
6) Where do your items ship from?
A: Albums and official goods come from South Korea and ship out of our small facility in Denver, CO. Unofficial and less expensive goods are made in and ship from China.
1) What's your return policy?
A: All sales are final. We accept returns for refunds, for items damaged in transit or defective items. Why? Returns run counter to our emphasis on sustainability: every return has a carbon footprint.
2) Can I cancel my order?
A: Yes, you can if it's within 48 hours. All orders cancelled after 48 hours are subject to a $20 administration fee, whether or not your order has shipped. If you order has shipped, you (the buyer) will also be responsible for actual return shipping charges. Refunds will only be issued to the original credit card that you use when placing your order.
3) What happens if I receive a defective electronic item?
A: Electronics include any product that requires a battery such as a Lightstick. In the rare event you receive a sealed official lightstick that is defective, you would need to contact the manufacturer. The contact information can be found in the user manual.

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.
