Bootleg Warning : Saber/Zero (Max Factory)
Below is one example of a bootleg figure, please note that is is only one possibility. You should always be on the look out for anything suspicious.
Also note that there can be bootlegs of various figures, not just the examples shown on this website.

The sticking-up hair on the official version is facing forward, but is bent in the wrong direction on the bootleg version.
The skin of the bootleg also looks much glossier when compared to the official version.

The holographic sticker is stuck on all official versions as proof that copyright permission has been obtained. It is missing on the bootleg version.
(Note that not all products have this, but Saber/Zero will always have this label.)

The holographic sticker is stuck on the back of all official versions. It is missing on the bootleg version.

The font used for the age restriction of the figure is much thinner on the bootleg version.
