My kits are for emergencies only and I have lots of reasons for this. I choose the items and pack them very carefuly (particularly in my smallest kit) to make them as small and light as possible and still higher quality and more effective than other simlarly used larger, heavier items. This also adds a great deal of expense with regards to a lot of the items.

That said I don't vacuum seal my kit or tape it up with 300 feet of 2 different kinds of tape either. However my reason for that is not so I can get in to my kit whenever I need something in contains in a non-emergency situation. The reason I make my kits relatively easy to open is so that I can get into them when injured and/or under a lot of stress.
