You can check whether there are bonuses when purchasing genuine albums, and confirm whether you need to purchase them additionally. If you need to purchase additionally, you can purchase them through official channels (such as the official website, Amazon, Tmall, etc.) or online malls (such as Yes24, Ktown4u, etc.).

Some bonuses may only be available on specific websites or malls, so you need to check the information carefully. After you purchase, you need to fill in the necessary information and pay the fee according to the prescribed process.

The bonuses usually come in the form of gifts, such as posters, postcards, stickers, etc., so if you are a true fan, these bonuses may be worth having.
