We love this one. In fact we love this fabric so much we're going back to buy some more and make cushion covers from it too for us.
Fortunately Boss or Lily don't have this collar in their wardrobe (yet) - they live on our settee and we're undecided whether them being camouflaged against the cushions is a good thing . . .

A 100% cotton fabric stitched on to tough webbing with chocolate brown satin lining. The 25mm (1") deep control loop is made from tough, high quality chocolate brown webbing.
Nickel-plated metalware and the D-ring is welded.
