For seriousness and to facilitate quick communication and completion of the sale on the same day: please send your number in private message so I can contact you via WhatsApp or direct call, as I will not be continuously present for app notifications. Thank you. "Peace be upon you. For sale: 20-inch bicycle tire (the inner rubber tube for air, brand new and in its box, never opened). No delivery whatsoever, pickup from my location only. Important notice to everyone: The price is final and absolutely non-negotiable (20 SAR), and no one should come to me saying 15 or 19. I am not interested in exchanges, and I will not reduce the price by a single riyal. The price is clear, and the pictures show the cleanliness of the item. So, whoever is serious is welcome, and others should not bother themselves."
