The size is entered as 80cm because it's a required field, but the tag doesn't specify the size, so the exact size is unknown. Please check the 9th and 10th photos. Since there are individual differences, this is just a reference, but The bibs seem like they would fit until around 1-2 years old, and the pants, being elastic, seem like they would fit until around 3-4 years old. Oni-patterned bibs are not very common, and they are very cute when babies wear them♡ They are made of a smooth material and are clean with no stains, but they have been worn a few times, so please refrain from purchasing if you are concerned about minor details. They will be folded small and shipped via Nekopos. Thank you for viewing.
