What about large gallon zip lock bags with owners info written on? Or for larger blades plastic or paper grocery sacks with owners, and blade info on index card?
honestly the best thing would be to go to the post office and get one of the free priority mail cadboard boxes and put them in there, because razor sharp knives and ziploc bags don't mesh well. and if you have any special needs or concerns just PM me would be the easiest way to figure those out.
You didn't kill it. I've just had a lot going on and haven't been able to make it here. If the plan is for tyler to pick them up, that works even better.
