Where to buy CORTIS photocards & merch

Buying guide

For collectors, CORTIS photocards and merchandise are distributed across four channels that matter for resale value and authenticity: (a) standard album versions sold worldwide through Ktown4u, Music Plant, and Weverse Shop, (b) pre-order benefit (POB) cards offered by individual retailers — each shop typically ships a different exclusive card, (c) fansign and lucky-draw cards, which are Korea-only and only obtainable by attending an event or buying through a Korean proxy, and (d) secondary market listings on Mercari, Bunjang (번개장터), and X/Twitter trade communities.

Before buying CORTIS photocards on the secondary market, treat every listing as a potential reprint until proven otherwise. Reprints are the single biggest risk for new collectors: they look indistinguishable in flat photos but show subtle differences in print texture, edge cut, and back-side ink under good light. Always ask for clear photos of the back, the corner cut, and a held-card video at an angle. For lucky-draw and fansign cards, request the original event proof or known seller history. We cover authentication signals on our verification guides — see the internal links above this section.

Direct from-Korea routes (Ktown4u, Music Plant, Weverse Shop) typically ship within 5–10 business days for Asia and 10–20 days for North America and Europe. Customs duties vary by country: the EU and UK generally charge VAT plus a small handling fee on parcels over the de minimis threshold; the US has higher de minimis tolerances; LATAM markets (Brazil, Mexico) often see longer customs holds. Plan release-week budgets accordingly, and prefer pre-orders over launch-day purchases when shop stock is limited.
