Yes, they work as all three: stress balls, hackey sacks, and juggling balls! Chain maille is such a tactile art, that they are perfect stress balls. They have a great squish factor, making them great to be used as hackey sacks. And they are fairly lightweight, making them quite aerodynamic to use as juggling balls.
Each ball has an approximate 2 1/4" diameter, is made with bright aluminum rings, and is filled with fabric making it quite easy to clean.
Available in Athena's Armoury Etsy Shop and Artfire Studio. Please contact me if you're interested in only one ball. More colors coming soon!!
