Could be a bit smaller. Difficult to transport when inflated.
Experiment. The ball lasted 30 minutes, a manufacturing error and it fell on us.
The tube to inflate just went in, but couldn't take it out again
for another variant: ZAHL 3
I had bought a 3 and a 0 for a birthday party, unfortunately I couldn't use them because the cardboard tube was bent in several places and the number couldn't be inflated... too bad
for another variant: ZAHL 5
