NIKE Authenticity Check | How to Spot Fakes & Date Tags | RE-USE TOKYO
RE-USE TOKYO
AUTHENTICATION GUIDE
Authentication Basics
Authenticating Nike items cannot be judged by a single factor alone.
It is essential to comprehensively examine four points: tags, care labels, Swoosh embroidery, and stitching.
Tag specifications vary greatly by era, from vintage to current, so confirming era consistency is crucial.
⚠ Do not judge based solely on the Swoosh or zipper. Tags and care labels are most important.
⚠️ Authentication Criteria Emphasized by RE-USE TOKYO
Tags (Era Consistency): Approx. 40% → Item number format, country of manufacture, tag design (silver/white/black), font
Care Label: Approx. 30% → Material composition, washing instructions, accuracy of legal notations, consistency with main tag
Swoosh Embroidery: Approx. 20% → Balance, uniformity, finish
Stitching & Material Feel: Approx. 10% → Stitch uniformity, fabric thickness, texture
※These are rough estimates based on experience, and judging factors may vary by product.
Swoosh Quality Differences
※Do not authenticate based solely on the Swoosh; consider it in conjunction with other factors.
✓ High-Quality Swoosh
- Natural balance of the entire Swoosh
- Careful finishing of curves and outlines
- Uniform thickness and placement
- Gradual change in thickness
✗ Low-Quality Swoosh
- Distorted or angular curves

- Overall too thick
- Awkward shape

⚠ Important Notes
Regarding Zippers: Nike officially uses zippers from multiple manufacturers besides YKK. Do not authenticate based solely on the zipper brand.
Regarding Item Numbers: Information for older models may not be available on official websites. Do not authenticate based solely on item number search results.
Regarding Vintage Nike: Tag aging is also a factor in authentication. For silver tag and white tag items, check for natural wear and tear appropriate for their age.
Regarding Korean Market Products: Korean-exclusive models or products distributed for the Korean market may have different tag specifications than the Japanese version. Do not dismiss an item as fake based solely on tag specification differences.
Regarding QR Codes: These may be seen on recent models, but for used clothing, do not authenticate solely based on QR code verification.
