Haven't used the new box yet, but the ones on my trays from a few years ago are getting that, although they still work, look well, in need of replacing. Excellent stuff

I have cut the in to three very large circles to usr on my pizza trays. They are brilliant and last for years. I just bought a new roll to replace the sheets I have been using for about 10 years. They get used weekly at about 220 degrees and have not lost any of their non-stick properties.

Nothing sticks to this. It is easy to cut whatever size and shape you need for baking trays and other things - I also have some in the bottom of my Remoska - which is recommended in the instructions. It stops things from scratching the bottom of the Remoska pan. Useful for biscuits and anything you are cooking, so they don't stick to the trays.

The last time I Purchased MAGIC REUSABLE NON-STICK BAKING TRAY LINER was 1998 and it's still going strong. It does exactly what it says on the tin. It's strong, durable, easy to cut and truly non stick. The only reason I'm having to buy more is because as the years go by, more tins make it into my collection. If this liner lasts as long as the other one, I think it's money well spent.

Initially this seems quite expensive, however, as it lasts years it saves money in time. Excellent non-stick properties. Easy to wash and re-use, can even be popped in the dishwasher. A repeat purchase I'm adding liner to all my regularly used baking trays.
