You know Save Express in Hamburg, Germany? They are a huge diaper shop and their warehouse is diaper walhalla.
Whenever I am there, I am soooo excited to just walk around amidst thousands of lovely diapers, rompers, adult pacifiers, I never want to leave the place <3
They literally have pallets ful of boxes full of packs full of diapers. And my favourite: the Sexy Adult Diaper. I love it!
