How to QC bags, belts, glasses, jewelry, and small accessories through ACBuy spreadsheets.
Table of Contents
Accessories span the widest quality range on any ACBuy spreadsheet. A $12 belt and a $140 rep bag sit in the same category, yet their QC requirements are completely different. In 2026, accessories have become a growth category as buyers move beyond shoes and apparel into bags, belts, glasses, jewelry, and watches. This guide focuses on universal QC principles that apply across all accessory types: hardware engraving, stitching consistency, material grain, and logo placement. We also break down category-specific checks for bags, belts, glasses, and jewelry so you know exactly what photos to request regardless of item type. Accessories are small details that make or break an outfit — getting them right matters.
Universal QC Points
Inspection Framework for All Accessories
| Hardware | Check engraving depth, plating consistency, and magnet strength. Shallow engraving wears off in weeks. Uneven plating indicates poor galvanization. |
| Stitching | Count SPI (stitches per inch). 8-10 SPI is retail range. Fewer than 6 SPI indicates rushed construction prone to failure at stress points. |
| Material | Grain regularity, color fastness, and edge paint smoothness. Good leather has irregular but natural grain. Perfectly uniform grain is usually PU coating. |
| Logo Placement | Alignment, depth, and font weight. Use a ruler in photos to confirm centered placement. Off-center logos are the most common accessory flaw. |
By Accessory Type: What to Request
Category-Specific Photo Requests
Bags & Backpacks
Request: zipper engraving close-up, interior tag font, stitching at strap attachment, grain close-up, edge paint photo, and strap hardware spring test.
Belts
Request: buckle engraving depth, belt hole spacing accuracy, tip shape, backside stamp clarity, and keeper loop construction.
Sunglasses
Request: hinge mechanism photo, lens etching close-up, nose pad attachment, temple tip detail, and UV label on lens if claimed.
Watches
Request: dial printing clarity, hand alignment at 12:00, crown engraving, caseback detail, and bracelet link finish consistency.
Jewelry
Request: clasp mechanism, chain link uniformity, stone setting security, and plating thickness at wear points (clasps, rings).
Common Accessory Mistakes
Red Flags by Category
- Bag zippers that skip teeth or require force to close. Test this in a video, not just photos.
- Belts with misaligned holes or uneven spacing between holes. Should be exactly 2.5cm apart on standard designs.
- Sunglasses with plastic hinges instead of metal. Plastic hinges snap within months of regular use.
- Watch bracelets with sharp edges between links. Retail watches have smooth, polished inter-link transitions.
- Jewelry with loose stone settings. Tap test in video — stones should not shift or rattle.
- Hardware that feels lightweight or hollow. Quality hardware has substantial heft for its size.
Safety Note: Sunglasses & Watches
Most rep sunglasses use UV400 polycarbonate lenses which offer adequate sun protection for casual wear. However, the coating consistency varies by factory. Budget batches may have uneven UV coating that leaves gaps in protection. For daily summer wear, stick to mid-tier or premium batches. Prescription lenses in rep frames are risky — the optical centers may not align with your pupillary distance, causing eye strain or headaches. Use clear plano lenses only. For watches, automatic movements in budget reps often have poor power reserve and accuracy. If you want a functional daily watch, research the movement type before buying. Miyota and Seiko NH35 movements are reliable workhorses. Unknown Chinese automatic movements are lottery tickets — some run well, others lose minutes per day.

Accessory Budget Tip
For accessories, spread your budget unevenly. Spend on items that touch your skin or carry weight: belts (pressure points), watch bracelets (daily wear), bag straps (load bearing). Save on items that are purely visual: keychains, phone cases, scarves. Construction quality matters most where mechanical stress occurs daily.
