Initially ordered the bulk bag of slate 40mm pieces as it's cheaper than local builders merchants/garden centres even with delivery added. Expected a similar quality to what we've had previously but this is SO MUCH BETTER-the pieces are much chunkier and heavier and it looks great. Should also add that the delivery driver-can't recall the courier used- was amazing ; our road was blocked with gas vans working on an emergency leak so he and my husband pushed/pulled the pallet down the road onto our drive. Would definitely use Grasslands Turf for other items for our garden project and would highly recommend them.
