The set includes one with a lion graphic, another with a black and white image of the Eiffel Tower and Arc de Triomphe in Paris, and a third black one featuring green cannabis leaves. 
Ashtrays can serve as functional items for smokers in various settings, but are also repurposed for other uses like spoon rests. 
Vintage or rare ashtrays are sought-after items for collectors and design enthusiasts. 
They are available in various materials such as glass, stainless steel, or ceramic. 
The items pictured are likely made of metal or glass due to their glossy finish and common use in ashtray manufacturing.
