This Sports Active card holds precisely what always goes missing first from a ball pump: the metal needles you use to inflate a football, basketball or volleyball, a flexible hose with a screw fitting at either end, and a black conical nozzle for inflatable toys with a wider valve.
The needles and the nozzle screw on; the hose in between gives you some slack, so you no longer have to hold the ball down with a knee while you pump. There is also a small connector that joins the needle to the hose.
Note that this is the accessory set only. No pump is included. Buy it as a spare for the pump you already have, or put it ready now, because the needle is invariably missing on the evening before the first match.
The parts sit in a clear blister on a card with a hanging hole, so you can keep them together in the sports bag or in the tool drawer without anything rolling away.
