Merries Diapers have been highly favored for their safety, dryness, and ultra softness for a long time. This is why mothers in many countries trust them.
Currently, there are various types of Merries diapers available in the market such as domestic products (parallel imports), imports from Japan, and Merries diapers originating from Taiwan.

For domestic products, the packaging is entirely in Japanese with specific Japanese symbols. Therefore, many mothers are concerned about the expiry dates of domestic Merries diapers. Mytour provides some information about symbols indicating the batch number, production date, and expiry date printed directly on the packaging. These characters are easily found at the bottom of the diaper pack.
The batch number symbol is formatted as: XXXX-YYY-Z.
The first 4 characters (XXXX) represent the production line code.
