Putting a string of LED lights inside your itabag will definitely make your bag look more cool.
These lights are 1 meter long, and have six colors available for you to choose. You can put these inside your itabag, making it flicker and shine, and it will look very beautiful.
Under normal temperatures, the batteries can be continuously used for about 50 hours. One string requires two batteries, and each string has its own battery. If you think that you will frequently use these lights, you can also buy them separately.
