This is a combination undergarment from Marmaille, a specialty store for baby underwear. Made in Japan, the fabric and sewing are very sturdy, so I think it can still be used. *Compared to the underwear from Nishimatsuya that I used when my baby was a newborn, the sturdiness is completely different!* No pets, no smokers. It will be waterproofed and shipped in simple packaging.
