BS646 Cartridge Fuses.
A small cardboard box which originally contained a half dozen fuses. 5 amp rating.
These are small fuses to BS646, and were typically used for shaver adaptors, clock connectors and the rare instances where BS546 round pin plugs actually had a fuse in them.
These fuses are Made In England to an incredibly low standard.
Wires can be seen protuding from the end caps, the labelling is paper which is peeling off, and the caps themselves are of an irregular shape.
