fragile free vector download

I work in a storage, so I need sometimes pictograms to declare goods. To looking for free pictograms in the internet, was the time where I stumbled upon openclipart and inkscape. I know it is easy to draw but maybe more usefull then dogs and pics of cars. ;) The pictograms on every brand look different but similiar. So i draw some importants and tryed to make it in little ways different. (copyright??) Every pictogram show the "dont wet" theme with an umbrella. I tryed to say the same with a roof and package. I hope you have some more ideas. Dont rate pictogram except u want rate the idea. ;-)
