This packaging is very, very wasteful. Before each use I have to twist the handle up to 30 times (with intervals) before something comes out, and it comes out a whole lot at once, way more than needed for just one application. If you intend on using it frequently, you may run out pretty soon.
It should last pretty long but I would advise washing after each application to avoid applicator getting stuck and gunky and just twist a click or two to avoid wasting product. They are definitely expensive, but are more of a special occasion product.
