Wholesale Foldable Kids Sunglasses – TR90 Flexible Frame, Custom Logo & Colors, OEM/ODM Available, Low MOQ
Sourcing kids' eyewear for your private label or retail line? This foldable kids sunglasses model is built on a flexible TR90 frame — a material buyers trust for low return rates, since it resists snapping under normal wear and holds up to shipping and handling far better than rigid acetate or PC frames.
The flat-fold hinge design reduces packaging volume for freight, and the gradient two-tone colorway is fully customizable: we can match Pantone codes, adjust the gradient ratio, or produce solid colors on request. Frame front, temple color, and lens tint can each be specified independently for private label differentiation.
Lenses are UV400 rated with test reports available on request, and frame material is compliant with standard children's product safety requirements (CE / REACH — confirm specific certification needs at inquiry). Logo customization is available via pad printing, laser engraving, or in-mold branding on the temple, with artwork proofs provided before production.
