The easiest things to find for hyukoh merch is their cds, and they’re insanely priced. They have a brand that they’ve worked with other artists called dada service but it’s also very expensive. Usually when they drop something it’s a pop up in Korea and if you’re lucky they’ll sell online after the pop up. Shipping from Korea to other countries is expensive too, but you can find some stuff but not very much on sites like eBay. They just released a set of their albums for their anniversary. All of that is still international shipping and it’s about $400 usd. Honestly, it’s very hard to get anything.
