It is very important for you:
No one is perfect, not to mention a toy. The quality of different batches of toys must be uneven. After all, the toy is just a kind of plastic product. All links including production, processing, packaging, logistics and so on may appear various losses such as flaking paint, nick, uneven color, ect. Which are common natural phenomena. Please do not judge a toy produced with hundreds of thousands of pieces and assembled by hand by the standard of Art.
