Since the product is 'no label' or 'white label,' the primary packaging (bottles/tubes) must be durable and aesthetically pleasing. Check for leak-proof designs and the quality of applicators (e.g., doe-foot for lip gloss or brushes for liners). If you plan to apply your own branding later, ensure the surface material is compatible with silk-screen printing, UV coating, or high-quality adhesive labels. Request samples to test the tactile feel and 'shelf appeal' of the packaging before committing to a bulk order.
