I used this when my children were toddlers to lower elementary school age for field trips, etc. I used it a few times a year. There are no noticeable stains, but since it has been used outdoors, there may be some minor damage. The color is turquoise blue. Please see the photos for the size. I am also selling a pink one. My siblings used them, and it was cute when the two of them were together. I will fold it up for shipping.
