This is a set of 5 baby hats. The front three in photo 1 are the tie-up type. Only the middle one is knit material. The yellow hat in photo 6 is from H&M, but the tag has been cut off. I believe the size and usage period were 6-9M. It feels a bit smaller than the pink hat. There are no noticeable scratches or stains, but please understand that these are items stored at home.
