I have a car seat from Nuna in America, from birth until 1.5 years old. I bought it in America at the time of birth because a car seat was required, and upon returning, it hasn't been used as another car seat was purchased before birth, and the base for it hasn't been used until now (14 kg). The seat is completely new, and the brand is well-known; however, the brand's name is unknown. The price is non-negotiable because the seat is completely new and I'm not in a hurry to sell it.
