■ Features of "SmartAngel Swim Diapers"
1. Won't swell in water! Supports comfortable movement
Since no superabsorbent polymer is used, they do not swell significantly like regular paper diapers when wet. This allows children to move comfortably and enjoy water play without hindrance. The outer layer is made of water-repellent non-woven fabric, and the inner part uses cotton pulp to temporarily absorb sudden urination.
2. Peace of mind for sudden bowel movements! Leg gathers securely block leaks
Equipped with deep leg gathers, these diapers provide peace of mind for unexpected bowel movements during water play. They fit snugly around the child's legs, preventing leaks.
*Please note that loose stools may not be completely prevented from leaking. Also, please use in accordance with the rules of public facilities.
3. Gentle fit around the tummy! Soft waistband
The soft waistband, designed with large pleats, gently fits around the tummy without tightening. Children can wear them comfortably, and they are characterized by not leaving marks on the stomach.
4. Cute appearance with a unisex light blue striped pattern
The refreshing light blue striped pattern design is suitable for both boys and girls. Children can enjoy water play in style.
5. Budget-friendly! Affordable price
We have achieved a low price of 988 yen (tax included) for 10 pieces of each size. At approximately 99 yen per piece, they are an economical choice that can be used without hesitation every time.
Moving forward, our company will continue to pursue product development that satisfies both functionality and price, meeting the needs of both parents and children, and supporting the daily lives of child-rearing households. We will strive to further expand our product lineup with an unwavering commitment to quality and price.
