It's not a quality problem. You need to take care of the return shipping fee. Free shipping products. You need to deduct the shipping fee (the total price of the order is deducted from the shipping fee). Please know before purchasing. I don't want to make trouble for the postage! If the transaction is not successful, there will be no free shipping. The freight is also paid to the courier company. It is not earned by individuals. Please understand each other! (Small commodities are very common daily products with color difference, uneven color, small flaws do not affect the use at all, don't shoot if there are high requirements) if there is any bad ones, you can take photos and send them to me, thank you for your cooperation! Wish you a happy shopping experience!
