I don't know yet, if I will buy my kit directly from ETS, but I will most likely throw away the clamshell packaging and carry only the kit on me. On the other side, some more aggressive inks may damage the vinyl and it will take more time to sign the pouch. <img src="images/graemlins/confused.gif" alt="" />

The sticker might be a good idea. You could print out an adhesive page with ETS logos, put your signature below or next to it, slice the page a few times and then throw one sticker into each pack.

Oh well, just sign the packaging, that's easiest and fastest. <img src="images/graemlins/wink.gif" alt="" />
