I've used these for a little over three months. The gray one is for 6-10kg, and the pink one is for 6-8.5kg, so there's a slight difference, but they're about the same size. I liked using them, so they show signs of use. Please refrain from purchasing if you are sensitive to used items, as they have been used and stored at home. If you're thinking of using them for only a few months and then discarding them, please consider these. There are no tears or damage. Soft cotton blend sleeper with a zipper for easy on and off. Thank you for looking.
