This uses a standard and simple slide-down-and-lock mechanism providing unlimited expandability and large amounts of flexibility to create S-patterns or complete circles. Each box contains 10 pieces of edging; these have 2 spikes per piece allowing strong rigidity in the ground without fear of slumping. Please note that any length selected above 2.5m will be sent as multiple boxes, for example a 10m length is 4 boxes and a 50m length is 20 boxes. 2.5m total length per box, 10 pieces per box.
