We already have a (wickedly expensive) Lakeland roll-up pastry mat and needed a second one for a holiday home. Loathe to spend big money again for something that will be used infrequently, we opted for this item.... which works fine, does its job exactly as described but DOES NOT roll up and is NOT a Silicone material. Rather, it feels like High density polythene or Polypropylene, both non-stick materials but quite rigid making the mat rather fun to use as a wobble-board when embarrassing people with your Rolf Harris impersonations!
Make sure that you have a suitable place to conveniently store it.
