This is a box of small metal hose clips, also called hose clamps, shown with two loose clamps beside the box. The visible marking is M00 BS/16 with a size range of 1/2 inch to 5/8 inch, about 11-16mm. These are used to secure coolant, heater, fuel, air, or vacuum hoses on many vehicles, so they are universal rather than tied to one car make. The photo shows new-looking metal worm-drive style clamps with screws, supplied in retail packaging; check the hose outside diameter before ordering. Make sure the clamp range covers your hose size and confirm the band width and screw drive type if you need an exact match.
