I'm a new dad, and had read that its a good idea to have nappy bags in your changing bag. A trip to Boots was a bit of an eye opener, as the price per bag was quite high. Amazon sell these at a much cheaper rate. The bags are:
+ easy to open
+ hold a newborn nappy and cotton wool used to wipe down
+ easy to tie up
On the down side:
- they dont really have a fragrance, but its not a problem. Just smell of bag really.
Very good value imho, will buy again, but with 300 bags in a box, it will be a while!
