www.saveexpress.de stock really good plastic backed nappies with leg-guards. Reasonably priced. They'll hold upto 4 litres and are very comfortable. Four resealable tapes which do work. They're a really good nappy. The company is based in Germany, but postage isn't excessive and they deliver within a few days outside of Germany

Just taken a delivery, I love when a new stock arrives, just reinforces how much I love and need my nappies.
I store them unpacked on shelves in my dressing room. Love seeing them stacked up, just waiting to be worn and used.
