About us

About us

Rialma was started in 1985 in Milan province, Italy, by Carlo and Antonella. It has grown over the years, originally supplying only products for packaging and the building industry, then for cake design. Now it is one of Europe’s leading party suppliers!

Rialma Party Ideas was founded to guide all party planners (as well as others) through the world of polystyrene structures for events.
With our machines we are able to work blocks of polystyrene and “sculpt” it according to the customer’s requirements.

As you will see in our store, you will be spoiled for choice, with letters, numbers, cylinders, pillars, various types of backdrop and much more to pick from.
The beauty of polystyrene is that it can be customized however you prefer; ask us for tips on how to colour or cover it.
Rialma Party Ideas is also on  Instagram at rialma_polistirolo, join our community!
