Double Ring Box Velvet Interior LED Light Magnetic Closure Wedding Band Set

Product Overview

Guangdong Bincai Color Printing’s double ring box is engineered for wedding band sets and dual-ring jewelry presentations. The integrated warm-white LED sensor light activates automatically when the lid opens — illuminating both rings against the deep velvet backdrop — and deactivates on closure. This creates an unforgettable unboxing moment that wedding photographers love and couples remember forever. ISO 9001:2015 & FSC certified manufacturing. 22 years of jewelry packaging expertise.

Sustainability & Compliance

FAQ

Q: How long does the LED battery last? Can customers replace it?

A: The CR2032 battery powers approximately 1,500 open/close cycles (3–5 years of typical retail/consumer use). The battery compartment is user-accessible with a small screwdriver — no specialized tools needed. We include a spare CR2032 and replacement instructions with bulk orders.

Q: Will the LED activate during shipping and drain the battery?

A: No. The photo-sensor LED module requires ambient light change to trigger — it will not activate in a dark shipping carton. We also include a pull-tab battery isolator strip (removed by customer on first use) as an additional safeguard for long-term storage and ocean freight.

Q: Can the velvet color be matched to my brand’s specific Pantone?

A: Yes. Our electrostatic flocking process matches to Pantone textile standards with ΔE ≤ 2.0 tolerance. 12 standard colors are available at no MOQ premium, and custom Pantone-matched flocking is available with a 1,000-unit MOQ. We provide velvet swatch samples for approval before production.

Q: Is the box suitable for both engagement rings and wedding bands?

A: Absolutely. The dual-ring groove layout accommodates both slim wedding bands (2–4mm width) and larger engagement rings (up to 8mm band width). The ring grooves are CNC-milled with a tapered profile that securely cradles different ring sizes. For solitaire engagement rings with prominent center stones, we can add a deeper center cavity to prevent the stone from touching the lid interior.

Q: What if I need custom branding on the LED module itself (color temperature, logo projection)?

A: We offer several LED customization tiers: (1) color temperature swap — warm white 2700K, neutral 3500K, or cool white 4000K at no additional charge; (2) RGB addressable LED for brand-color illumination — available with 1,000-unit MOQ; (3) custom logo projection lens — projects your brand logo onto the ring tray when opened — MOQ 3,000 units. Our in-house electronics integration team handles the full design-to-production workflow.
