So you got a thing for Italian snacks? The XIANGJ Arancini Maker is a handy tool that lets you make perfectly shaped rice balls from 80 to 160 grams. It can make these treats in two shapes. To get started, fill the base with rice, put the lid on the base, and push the plunger in, remove the plunger and add your filling, and cover the top with a thin layer of rice.
This mold is made of non-toxic plastic materials. You can find out more about it here.
