EasyFlex Snip-to-Flex Paver Edging, 60-Feet, Black

Q: Are the included spikes metal or plastic?

Would be nice to make it clear on item description that soikes not included ..opened box ready for edge instsll and no spikes

Q: The measurements do not seem to make it clear what is the vertical height of the edging? I want to use it to separate 2 colors of rock 2-3" deep

It is only 1 1/4" high. If I had realized that, I would not have bought it.

Q: Do you need the connectors for this product like the ones that are included with the other kits by this company?

Sand will seep out at the connection, or you can overlap the 2 bars to leave no space between them. It will not look perfect for the bar has some thickness to them, and you will need to pack some soil under the bar that is on top because there will be a space under it if you overlap the bars. Also you will not be able to nail the two bars together because the holes will not align. I can see this being a problem when the overlap occurs on the curvy part of your path. I do not think I have seen connectors for this product, or that I did not look hard enough. I kind of solve that problem by using polymeric sand, hoping that the sand will hold together by itself instead of seeping through the connecting point. I had my garden path for less than a year, so I can't say whether this will hold up well or not.
