This unisex light-up cap with an adjustable strap fits almost everyone and is easy to wear. It produces no heat, emits no radiation, is harmless to the human body, and is durable.
A single switch controls seven colors and five flashing modes: red, green, blue, gold, light blue, purple, multicolored; and solid, flash, gradient, and smooth. The vibrant light design is undeniably eye-catching.
The USB rechargeable battery is reusable and provides 6-8 hours of operation after a 1-2 hour charge.
It can be gently hand washed with water up to 50°C and natural soap (scrubbing only, do not knead or twist). However, the battery compartment must be removed before washing or kept away from water. If the battery compartment is removed, keep the power cable away from water. This fabric should not be machine washed. Do not use in a tumble dryer or iron. Hang only to dry.
