Bulb card (BC125, BC150)

The size same as credit card and no wire needs. It is very convenient because it can place inside the wallet.

A such small card may use for illumination, design is so funny.
The interior has a LED light bulb, when you need to illuminate, you just fold "Light Bulb" up then the light turns on. If put " light Bulb" down, then the light turns off.

You can use it anytime and anywhere!!!
