And the variety do makes me confused.
BUT lastly I choose to buy the Pink one.
When I first using it, I figured out it was so hard to be washed off.
And I wonder if there is any good way to wash off these "rubber" without pushing too much stress on your scalp.
Anyway, for those who using Gatsby moving rubber must spread the "rubber" on the tips of your hair and NOT scalp.
This is always an important thing to be noticed !
Anyhow, looking forward for the clues of using Gatsby Moving Rubber ;p
