The Teknic (sp) ones from the UK that are readily available out here are made in bulk hence the low price tag but you get what you pay for.
Their matts are a pretty low quality & the material hem round the outside does not sit flat.
So the custom made ones have a Nitrile rubber backing & edge with a polyester woven (like short carpet) top where the print is.
we are going to be looking at about $140 -160 each + postage depending on the qty we order.
Warning, there are cheaper ones on the market but research has shown that they dont use Nitrile rubber & can leach toxic chemicals from the rubber over time & the quality of the printing is pretty crappy... rather not use them

seems the process for manufacturing is not easy & is reflected in the pricing.
