The C.L. Morgan Co., where I got the small amber glass vials to repackage Potable Aqua for my mini-PSK, also offers a "sample pack" of their various sizes of zipper top plastic bags for $2. They included that with my order, and the smaller ones have proven very useful for segregating or waterproofing various bits of my mini- and large PSKs. Here is a link to their ordering page: CL Morgan .

Yep, I'll second that. I got the sample pack along with some tiny amber bottles. The bags are good quality, and you won't believe how small some of them are. You need tweezers to open them!

That's true. Here is their size list, all in inches:
SQUARE: 3/8, 1/2, 5/8, 3/4, 1, 1 1/4, 1 1/2, 2, 3
RECTANGULAR: 1 1/4 x 1, 1 1/2 x 1, 1 1/2 x 2, 2 x 1, 2 x 3
They come in green, blue, black, red, yellow or clear, so you can color-code your stuff at the same time you waterproof and segregate it. Not that I've ever done that ...

Small zip lock bags must be sold in stores,try some inner city stores,or "head shops".The drug dealers must buy these bags by the boat load.

The streets around the firehouse,and in fact the front yard of the firehouse are littered with them.

If I get a chance I'll axe the dealers across the street when I go in Fri. night.

My wife works at a Dollar Tree and I found a package of ziplock bags 16 2x3; 17 3x5, 17 5x7 for $1. I have not chedked on the quality but I thought I would pass on the information. the item code is 36477 00883.

I got them a bit ago and find them to be adequate for sealing and keeping things water tight. Dont try to pull them out of the pack by a corner as they will stretch and tear but if you have them inside a stuff sack keeping things organized they should be just fine. I use one for my bathroom kit and when I tried to pull it out of the pack by itself while it was squashed between things it ripped out.

Also check out the sewing repair kits, they are real handy. Pete

They have several items that I have gotten over the past few months -- 8 pk of emergency candles, sewing kit, eyeglasses repair kit, hobby knife kit, safety goggles, first aid items, small flashlights to keep in truck or pocket and many other items like that used for camping etc.
