THey're like normal bricks but without the holes. We have some on their ends, not that deep, but they're tight enough that when I gave the lawn a good soaking very little seeped through into the empty bed the other side. The other border, they're laid flat with a curve, I'll post a photo if you like. We'll be using the ones on their ends to hold in a 'deep bed' for veg.
