Admittedly, I have not subscribed to Birchbox France. It costs 13 €/month (compared with $10/month in the U.S.) and almost all of my money is going toward traveling--in fact, a one-month Birchbox subscription here would pay for a train ride to Paris! Still, I couldn't resist visiting the pop-up shop and seeing what it was all about!
There was a shopping station, atelier (workshop), free Løv Tea, and a BYOB (Build-Your-Own Birchbox) area! Of course, I took advantage of it all.
I ended up buying a clay face mask and made my own Birchbox for 15 €. I even got extra samples!
