12 Nike long Sleeve Onesies with matching pants

There are a total of 10 Long sleeve Nike onesies, 1 long sleeve Puma onesie, 1 t-shirt Nike onesie, and 9 Nike pants. Some show signs of wear, most are in good condition. All of them are size 3-6 months except for 2 which are size 0-3 months. I would like to keep these together and not separate them.
