Rei

Rei (real name Rei Naoi) / 나오이 레이 is a member of IVE, a k-pop group debuted in 2021 under STARSHIP, born in 2004. Their position in the group is lead rapper · vocalist, a role that typically shapes how their photocards and stage presence are framed across album promotions.

As part of IVE, Rei has been featured across the act's 5 years of release history, with member-specific photocards and concept visuals issued for each comeback. DIVE typically collect across multiple album versions to complete a single member's photocard set, since each retailer (Ktown4u, Music Plant, Weverse Shop, Korean shop POBs) usually offers a distinct exclusive card per release cycle.

Rei is currently primarily known for group activities; solo or sub-unit work has not been indexed here at this time.

Building a Rei photocard collection at any meaningful scale requires understanding two things at once: the structural rarity of K-pop photocards in general, and the specific market dynamics around IVE as an act that represents the highest level of mainstream visibility, chart performance, and global fan engagement. The structural side is the same for every K-pop collector — standard cards (one per album opening, member assignment varies by version), retailer pre-order benefit cards (POBs from Ktown4u, Music Plant, Weverse Shop, Soundwave, Apple Music, plus rotating Korean partners), Korea-only Lucky Draw cards (sealed-box randomized pulls at Korean offline shops), and event-driven cards (fansign attendance, pop-up store exclusives, broadcast event cards). The act-specific side, however, is where the real collector knowledge lives.

For Rei cards specifically, the most important variable is per-era visual identity. IVE's comeback eras typically split visual concepts across members so that each member has a "concept lane" within an album — a specific styling, hairstyle, color palette, and photo direction. Cards that align with the most photographed or most on-brand era for Rei tend to retain the highest secondary-market value over time, while cards from transitional or off-concept eras often trade at significant discounts to peak-era equivalents. Watching the music video for an album you are considering buying is the fastest way to gauge which version's photocards will most appeal to your collecting taste.

From a market-mechanics standpoint, Rei cards trade on a few key signals: era significance (debut-era and Lucky Draw cards typically command the highest premiums), card type (fansign and event-exclusive cards are rarer than standard or POB cards), and member visibility within the comeback (cover-card members and music-video-centered members typically hold higher prices than members who were rotated to backline positions for that particular era). For collectors playing a longer game, the most asymmetric value historically comes from buying mint-condition early-era cards before the act's tier-level visibility increases — once a group ascends from Tier B to Tier A or from Tier A to Tier S, the entire back catalog gets re-priced upward, and the cards bought during the lower-tier window become disproportionately valuable.

Rei's photocards are produced across the same four-channel structure as the rest of IVE: standard album versions (one card per opening, member assignment varies by version), retailer-exclusive POBs (Ktown4u, Music Plant, Weverse Shop, Soundwave, Apple Music, plus rotating partners), Korea-only fansign and lucky-draw cards, and event-specific cards from showcases or pop-ups. The completionist target for a single member set in any given comeback typically falls between 8 and 30 distinct cards depending on how many retailers carried that release.

Secondary market value for Rei cards is driven by three factors: (1) which era the card is from — debut-era cards and Lucky Draw cards tend to hold the highest premiums, (2) rarity within the print run — fansign cards and event cards are typically rarer than standard POBs, and (3) condition — high-grade (mint, no edge wear, no surface marks) examples can command 3–10× the price of moderately played copies. When buying Rei cards on the secondary market, always insist on clear back-side photos, edge close-ups, and a held-card video before payment.
