- We make sizes 5 and 4.
- Match balls must be 68–70 cm round and weigh 410–450 g at the start of a match, under the rules for match balls. Sizes 4 and 3 follow common guidance.
PRESSURE
Velarc balls play best at 0.8 to 1.0 bar. The rules for match balls allow 0.6 to 1.1 atmospheres at sea level.
CARE
Wet the needle before it goes in the valve. Dry the ball at room temperature, never on a radiator. Wipe mud off with a damp cloth; no solvents. In the off-season, store it a little soft and out of the sun.

QUESTIONS
Is Velarc real?
No. Velarc is a fictional brand, and this store is a live demo by Frustum. Nothing is charged and nothing is sent. The flight numbers are real: they come from published wind-tunnel data.
Which ball should I buy?
Three questions and the numbers: Which ball? →
Can I use a size 5 ball for under-12s?
Size 4 is lighter and smaller; it's the usual size from 8 to 12.
