Q:My toddler keeps putting little holes in the table silicone mat with his fork! is this thick enough to keep that from happening? A:Hey there, We are expecting here in the next 2 weeks, they are a nice thick mat and I think it would definitely help keeping the fork from going through them. Q:How thick are they? It says .1cm and also .9cmA:they are very thin, about .1 mm making them easy to fold so they fit the side pocket of a lunch bag really well.
