So handy and practical to carry with you!
1- Hold firmly the main metallic part and puch the pin until the end of it (Picture A)
2- Use the other hand to inflate repeatedly squashing the black rubber part of the pump. (Picture B)
3-Pull out the pump using the metallic part WITHOUT pulling the clack rubber part of the pump (Picture C)
N.B.- During the inflating process the metallic part must be always held in your hand pushing directly to the gym ball.
