Magical comb / comb

Remember the toy we played when we were all young?
The ruler curled on your wrist as soon as being knocked.
We use the feature of the material and make it as a hair bands.
When people need a comb, they could take their hair bands off, knock it, and a comb shows up.

Now, you have no need to bring a further comb. The magic comb will surely be the most functional decoration for the girls when going out.
