Tommee tippie dummies - storage question

[InsomniaQueen]

I bought some tommee tippie dummies, they come in a plastic box which I assumed I could use to sterilise them in the microwave and store afterwards. I just opened them and the instructions say not to use the box to sterilise or to store.

I have a steriliser which is fine but I'm not sure what to do with them after - anyone else just used the box anyway? This is my first LO so I'm paranoid worried about following the instructions for everything!

Thanks for your help.

Air dry them
under a food net on a paper towel and then fine 2 store in the box, which i would milton first.

Boots do a plastic box that you can add a bit of water in with the dummies, microwave for a few seconds and dummies plus box sterilised. Only a few quid and it was brilliant.
