This is an injection-plastic kit of a science-fiction/anime item.
Adapted from Good Smile Company's website:
From "Mobile Police Patlabor" comes a 1/60 scale plastic model kit of the ARL-99 Helldiver! It has been carefully and faithfully recreated based on its appearance from the series. The model boasts several points of articulation, and its dive brakes can be displayed while open. A 40mm cannon, combat knife and spare head part are all included. The model is made from ABS and PS plastic. Its various parts have been separated into different colored runners, and pre-painted parts and water-slide decals are included, making it easy to recreate the robot from the series with a simple assembly.
