There are 2 sizes in the Stelton Cylinda-Line Stainless revolving ashtray. Keeps unwanted smells and ashes beneath the bowl with a flick of the wrist. Like so many pieces in the Cylinda-Line, this piece is pure, simple, easy to use and perfect. A true Danish modern design classic designed by Arne Jacobsen. The Cylinda-Line was a groundbreaking series when it hit the market in 1967 winning the ID design award. It was so advanced that new machines and welding techniques had to be developed to accomplish the remarkably smooth, cylindrical stainless steel surfaces, devoid of any tension lines. The Cylinda-Line is a perfect example of functionalist design.
