Training pants set of 5 Two train and car pants are 90cm Three Shinkansen (Doctor Yellow, Kagayaki, Hayabusa) pants are 100cm. The 90cm ones are waterproof and sturdy, and rarely leak. I think it's a good idea to train well with the 90cm ones and then switch to the slightly thinner 100cm training pants! Please note that these are not new. - Colors: Blue, Yellow, Green, White - Design: Vehicle print - Size: 90cm - Material: 100% cotton - Quantity: Set of 5 Thank you for looking.
