The Marinierspritze can be filled with up to 50 ml - this amount is also sufficient, otherwise you can just reload again. The Marinierspritze sits comfortably in the hand and also the curved handle facilitates spraying. The needle itself has two openings, one on the front and the other on the back, so that product can be evenly marinated or stuffed. Cleaning the cannula is a bit cumbersome, but doable. ;)
