Which is probably a pretty standard design. Any idea if you can buy clips that fit over the sides to lock it? As I think my little boy might be trying to 'help out' soon too! Seems a shame to buy a whole new bin - I am sure I've seen clips somewhere...?
I went into Wilko's looking for a nappy bin and saw the one you're talking about. They've just done the shop out, so I assumed the red bin/green lid thing was some stuff they'd found out the back somewhere What's it really all about then??
