Garden edging (Seaton Delaval NE25)

Edging for lawns, beds or paths. Old and faded by the sun but still does the job well. Could be handy in an allotment to separate beds ?
There are around 20 of each style. Approximately 22cm in length, they slot together to make a full edge. The ones with extra flat part can be cut over with mower to make an easy edge to grass.
