Bulk Sourcing Designer Sunglasses: Specifications Buyers Should Verify

Before placing a bulk order for designer sunglasses, buyers should assess both the product’s appearance and its documented performance. Key checks include frame construction, lens protection, comfort, durability, customization, and the supplier’s ability to meet production and delivery requirements. The available listing describes a retro, small-round frame with rivet accents and a UV400 claim, but leaves materials, measurements, minimum order quantity, and lead time unspecified.

What to Confirm Before Ordering

• Review a sample for the listed small, round shape, rivet details, and overall finish.
• Ask for exact frame and lens materials, dimensions, fit information, and durability specifications.
• For branded production, agree on logo location and application, color choices, artwork approval, and any mold requirements.
• Request written confirmation of order quantities, production timing, quality checks, packaging, and shipping arrangements.

Product and Performance Review

The model is presented as retro-style sunglasses for men and women, with a compact round frame, decorative rivets, an option for a custom logo, and UV400 lenses. These details describe the intended design, but the listing does not provide material grades, frame or lens measurements, available colors, or model-specific test results. Obtain those details and compare them with an approved sample before authorizing production.

Performance should be assessed separately from appearance. Ask the supplier for documentation of the UV protection claim and any relevant impact-resistance testing. Also evaluate frame comfort and how the product holds up during regular wear. Yiwu Green Shine Arts & Crafts Co., Ltd. says its R&D and production work covers testing, mold development, material upgrades, color matching, and custom designs. These company-wide capabilities are not a substitute for specifications or test evidence for the particular sunglasses being ordered.

Production capacity and order terms also need to be considered together. The company reports annual output exceeding 3 million pairs, but the product listing does not state a minimum order or delivery schedule. Ask for a quotation covering sample approval, production milestones, inspection standards, packaging, and shipping costs and timing.

Frequently Asked Questions

Are the frame and lens materials identified?

No. Request material details for the specific model and verify that the approved sample matches those specifications.

Does the listing include proof of UV400 protection?

It states UV400, but no supporting report is provided. Ask the supplier for test documentation linked to the product being purchased.

Neither term appears in the product information. Confirm the minimum quantity and expected lead time directly before ordering.

Recommendations for Buyers

Use an approved sample to check the round frame, compact proportions, rivet accents, logo execution, and finish. Before committing to production, obtain written confirmation of materials, lens test evidence, order quantity, lead time, inspection criteria, packaging, and shipping terms.
