Day designed this back in 1955 as a small cocktail tray, but updated it later in life for a variety of uses. It's back once more, the work of retailer TwentyTwentyOne and personably an exclusive for that store.
As for the tray itself, it is classic Robin Day, with function meeting style thanks to those subtle curved edges and a want veneered plywood construction. Branding on the rear too, just in case you want to show off to your friends, not to mention custom packaging.
If you want one, it retails for £85.
