Silver coloured ABS 3D filament.
This standard diameter, 2.85mm, filament is well suited to the majority of 3D printing jobs.
ABS is a tough and strong plastic that resists high ambient temperatures.
It is an excellent material for printing pieces that are expected to through a lot of wear and tear but it does not print sharp edges or fine details very well so it is less suited to making decorative pieces.
ABS remains flexible to some extent after printing so it is quite easy to work with.
