Wa'alaikumassalam! Okay la, botol Avent 9oz yang lightly used dengan puting baru macam tu boleh jual, banyak second-hand mums cari especially yang dah nak wean off or switch bottles, so should find buyers easily je. Just be clear in your listing yang satu barely touched and one brand new, and mention the puting is new, that's actually a selling point because parents memang suka dapat botol + fresh nipple set. Good luck with the letgo!
