Character...Children's characters Yellow is made of polyester. Beige is made of cotton and polyester. The polyester one is thin and can be folded, so it doesn't take up much space and is easy to carry. I think it's also convenient as a bath bag for school trips, etc. How about a souvenir for a host family of someone studying abroad? Please refrain from purchasing if you are concerned about minor details. #Pikachu #Homestay #Pikachu #EcoBag #Pokemon
