Japanese diapers MERRIES are the No. 1 diapers for babies and children in Japan, the United Kingdom and Europe. MERRIES diapers stand out from other Japanese diapers with extremely high breathability: the diapers are made up of 3 layers that ensure maximum air circulation. As air circulates, excess moisture and heat evaporates through the micropores of the outer layer. This is what helps to prevent skin irritation, rashes and redness, which cause great discomfort to babies and worry for parents. Manufacturers use the best technology to make MERRIES diapers extremely liquid absorbent, yet thin and soft. The diapers are designed so that the liquid enters the special absorbent layer and does not come into contact with the baby's skin, thus avoiding possible skin irritation. These diapers use safe, high-quality materials free of formaldehyde (very many children are allergic to this compound specifically), phthalates, chlorine compounds, which is given away by the smell of the diapers. MERRIES diapers are odorless, no additional fragrances are used to mask chemical odors. The breathable reusable stickers firmly secure the diapers and help prevent liquids from leaking and do not chafe the baby's sensitive skin. The moisture indicator on the diapers shows parents when itâ??s time to change them: when the diapers are full, the moisture indicator changes color from yellow to blue.
