125x125mm, This is a must have tool especially if you are working on small helicopters or with small parts. The two sides of the tray are magnetic but have a soft inner so parts do not bounce off them and are easy to pick up. ...
The tray is split into three sections so your parts can be kept separate. They also have nice rubber feet to stop them slipping on the bench..... Definitely the most useful tool i have used in ages.
