The fragrance is any mixture of marine particles (sediments) plus a little Acocado (oil, skin care) plus indefinable. Smells masculine, harsh, a bit for shells. Reminds me of the North Sea. Fortunately, no aluminum is - as in many deodorants lately.
The closure is a bit fiddly (you first need to pull a ring). But you get used to it. The 4-pack price for around 10 EUR I personally priced okay. Since I have generally no problems with skin irritation, etc., I get along well with this product.
