By the power of a quick search, I'm told that 3.6 OZ is actually 102 grams, while 3.3 OZ is 93.6. 96 grams is 3.38 OZ, so one has to assume they're starting from grams and rounding down (even though they'd be justified to report 3.4 instead, honestly). It's not fluid ounces because that'd be somewhere in the region of 5, again according to search.
So most likely, it's a typo of some sort, or proof that non-metric systems should be banned by all humanity. This is also how European basketball players grow several centimeters when they start playing in the NBA.
Interestingly, pictures of the product online alternately show 104 and 96 grams. Volume wouldn't have to change, because you can just pressurize the can less to include less product. Oh, and yet another search tells me the reported net weight should not include the weight of the propellant.
Also, what are you doing buying Beckham's spray deodorant? Multiple times? I mean...
As far as buying multiples im alllergic to something in some deodorants and i get rashes under my arms.
This one hasn't so I have been using it for over 10 years. I have many many cans in the cupboardbecausewr buy them when they come half price.
Oh, no, I'm mostly joking. It's just... celebrity "lifestyle brands", you know? Or maybe you don't know. I'm certainly the type of person that buys "deodorant" brand deodorant, I may be the outlier here.
I eventually found out that it was a "72 hour" deodorant that I was reapplying every 24 hours (after my shower where, I assure you, I was washing my pits) and it was building up. It was so itchy and I'd scratch until I was raw.
Now I only wear it every other day and use a "natural" deodorant in between.
Just to add; it's clearly measured by weight because 150 ml is 5 fluid ounces.
And my comment, buy unscented deodorant and an actual bottle of cologne, it smells nicer.
