These amazing new nappy pods are 16cm by 17cm by 26cm. Great for out and about 
 
You can fit 6-8 nappies in them depending on the amount of inserts inside. 
They have a strong handle that un snaps to get around your pram handle.
They have 2 layers to them, an outside PUL layer and a inside PUL layer 
They are waterproof but the zips arnt so if you have very wet items against the zip they will leak.
