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, give your everyday wardrobe a MIGHTEEZ moment with the ATEEZ MIGHTEEZ x COLLER Rock The Stage T-shirt. This official short-sleeve tee brings the collection's rockstar theme into a wearable piece, with the MIGHTEEZ characters gathered across the front graphic.
Design details: a dark short-sleeve crewneck T-shirt with red MIGHTEEZ and Rockstar lettering, character illustrations, a star motif and lightning details on the front. Official photographs show a plain back. Pair it with jeans, a casual skirt or your favorite outer layer for fan gatherings and everyday outings.
Our supplier calls it Lights On POP UP — T-SHIRTS; the official Korean store identifies it as MIGHTEEZ x COLLER Rock The Stage T-shirt. The supplier name refers to this collection item. Styling props and other merchandise in promotional images are not included.
One Size only. Compare the published dimensions with a T-shirt you already own before ordering. We do not assign an unverified US S, M, L or XL equivalent, and one size does not guarantee the same fit for every wearer.
Included
1 × MIGHTEEZ x COLLER Rock The Stage T-shirt — One Size.
No standard photocard, extra preorder benefit or retailer event gift is confirmed. Benefits offered at another retailer or the original event do not automatically apply to KPOP Exchange orders.
Why ATINY Will Love It
Character artwork you can wear: the MIGHTEEZ lineup appears together in the front graphic.
Rockstar-inspired design: red lettering, star and lightning details give the tee its collection identity.
100% cotton: an all-cotton fabric composition confirmed by the official stores.
Easy outfit building: short sleeves and a crew neckline work with an existing casual wardrobe.
Official collaboration: part of the MIGHTEEZ x COLLER Rock The Stage pop-up range.
Enjoy it as a practical addition to your ATEEZ merchandise collection or as a gift for an ATINY who likes wearable goods. Check measurements before buying for yourself or someone else; the product photographs are useful for the design, but cannot guarantee a particular fit on every body.
