The injection set consists of an injector and 2 unscrewable stainless steel needles with a length of 6.5 cm. The best way to inject is to make one hole and from this hole push the needle down at two or three angles. This way you can inject in multiple directions without making multiple holes. The syringe is not dishwasher safe but is easy to clean because of the removable needle. Marinating has never been faster or easier.
