Don't worry if you smash this vase by Dutch designer Mianne de Vries â€“ a back-up vase is waiting inside.
Between two and four differently shaped vases are fitted inside each other to create each Curious Vase.
"The only way to discover what is inside is to destroy the vase," says de Vries. "But if you destroy the vase to find out what's in it, there is no turning back."
De Vries recently graduated from the Graphics and Product Design course atÂ Utrecht School of the Arts.
