8530 Masks is a BIONICLE set released in 2001. It contains five pieces: A head (comprised of a face and brain), a TECHNIC axle, and two Kanohi masks.
This set was sold exclusively in Europe and packaged in a polybag, unlike 8525 Masks, which was sold in North America and packaged in a box.
This set could contain the twelve main masks in their six colours, gold and silver Toa masks, or the mask of time.
This European version could also contain 14 different rare error "misprint" masks: the Matatu in the six Toa colors, the Ruru in the six Toa colors, the Kaukau in transparent yellow, and the Kaukau in transparent clear.
