I've changed this to just the Anpanman pants! I'm offering a great price for a bundle deal^_^ Regarding usage, I've used each pair about 5 times♪ Blue pants size 95 Yellow pants size 90 Please note that the sizes are different♪ Please be aware that there may be some slight pilling. Please purchase only if you understand that these are used items. Shipping will be done by folding them up small and putting them in a compression bag, so please excuse any creases.
