Graco Car Seat, Stroller, & Base. Date of Manufacture was 12.28.16, therefore expiration wouldn't be until 12.28.22 or later (depending on 6 or 10 year). Everything in the seat is freshly washed for new baby. Smoke-free and pet-free home. Stroller was only used a few times, because I had another stroller for both of my children. PPU in Pace near 5-Points.
