The QC Framework

Top CNFans Spreadsheet reviewers don't guess about quality. They follow established standards developed through thousands of product evaluations. Here's the framework.

Stitching Standards

Acceptable

• Consistent stitch length (2-3mm)
• No loose threads visible from arm's length
• Straight seam lines with minimal deviation
• Secure bar tacks at stress points

Rejection Criteria

• Skipped stitches anywhere visible
• Puckering along seams
• Uneven thread tension
• Missing reinforcement on pockets

Logo Accuracy Standards

Embroidery

• Letter spacing must be uniform
• Thread density should hide backing completely
• Colors must match within one shade
• Clean edges with no fraying

Print

• No cracking on new items
• Sharp edges without bleeding
• Proper opacity (no see-through)
• Centered placement within 5mm tolerance

Material Quality Markers

Cotton

• Weight specified and accurate (GSM rating)
• No pilling on new fabric
• Even dye saturation
• Appropriate stretch recovery

Leather

• Consistent grain pattern
• No chemical smell after 48 hours
• Proper edge finishing
• Hardware securely attached

Hardware Standards

Zippers, buttons, and metal components reveal manufacturing quality instantly.

Acceptable

• Smooth zipper operation
• Buttons sewn with cross-stitch pattern
• Metal weight appropriate to claimed material
• Engravings clear and deep

Red Flags

• Sticky or catching zippers
• Lightweight hardware on premium claims
• Shallow or blurry engravings
• Tarnishing visible on new items

Photo Documentation Standards

Quality reviewers capture evidence systematically.

Required Shots

• Full item front and back
• All logos and branding close-up
• Tags and labels
• Interior lining
• Hardware details
• Stitching samples from three areas

Lighting Requirements

• Natural light preferred
• No direct flash that obscures details
• Color reference card for accuracy

Grading Scale

Most trusted reviewers use consistent ratings.

• GL (Green Light): Meets all standards, recommend shipping
• RL (Red Light): Fails critical standards, recommend exchange
• Conditional GL: Minor flaws acceptable for price point

Price-Quality Calibration

Standards adjust based on what you pay.

Budget Tier (Under ¥100)

• Basic accuracy expected
• Minor flaws tolerated
• Material shortcuts understood

Mid Tier (¥100-300)

• Accurate details required
• Quality materials expected
• Minor flaws only on non-visible areas

Premium Tier (¥300+)

• Near-perfect execution required
• Premium materials mandatory
• Any visible flaw warrants RL

The Verification Process

Trusted reviewers follow consistent methodology.

1. Compare to retail references
2. Check batch-known flaws
3. Evaluate against price tier
4. Document with standard photo set
5. Provide clear GL/RL verdict with reasoning

Community Enforcement

These standards work because the community enforces them. Reviewers who GL clearly flawed items lose credibility. Those who maintain consistent standards build trust that drives the entire ecosystem.
