Introducing the "Biore u Foam Stamp Hand Soap, which comes out with flowers", which has three-dimensional bubbles in the Biore u hand soap. It is currently sold in advance at some online shops such as Amazon.co.jp and Rakuten.
A hand soap that uses a pump head that produces three-dimensional foam so that even children who are not good at whipping can enjoy washing their hands. By pressing with your hand from above, flower-shaped bubbles will stick to your palm like a stamp. The result is a little blurry, but every time 5 petals appear properly, even adults can enjoy the process of turning their hands around and checking the stamp.
If bubbles accumulate on the pump head, it will not be possible to clean it, so if you notice it, wash it with water. Even if you make a mistake, you will be motivated to ask, "Can you do it well next time?", So it seems that your child will get into the habit of washing their hands.
The appropriate age is around 4 years old, and it is scheduled to be sold in limited quantities at some drug stores from June 3rd. It seems that you can enjoy it even more if the variation of bubbles increases!
