These are pants from the NEIS gymnastics class. I used to attend, but I quit. The pants are still in good condition, so I'm offering them to someone who can use them. The size isn't written on the pants themselves, so I'm not certain, but the top uniform is size 100, so I think these are also size 100. My child attended when they were 2-3 years old, and the size was just right then. There's a loose thread on the front (see photo 3), and there are marks from a name sticker on the tag (see photo 4). Please consider this item as used. Thank you!
