Each charging case of FreeBuds Lipstick is made from fine steel, crafted from 100 metallurgy operations to create a smooth, metallic surface. Steel is prone to scratches and wear and tear caused by hard objects (such as jewelry and keys) or abrasive objects. To avoid damages, it is recommended that you use a velvet bag or other protective coating.

The charging rings on the WATCH Buds earbuds are electroplated with fine metal. When placed in the case, the charging rings may scratch and be scratched by charging points in the compartments, causing slight discoloration after a period of time. This is normal and does not affect the use of the earbuds. To minimize wear and tear, it is recommended that you clean the earbuds regularly, and avoid placing them with hard objects.
