This handy Plate Surround has a simple snap-on action that makes it suitable for use with plates ranging in size between 230mm and 280mm, or approximately 9 to 11 inches.Once in place, it provides a useful fixed edge against which food can be pushed in order to load it onto a fork or spoon, so it makes a useful aid to one handed eating. Another benefit of the Plate Surround is that it helps to prevent foods from being pushed off the edge of the plate and onto the table.
