Steve Spangler Science Large Plastic Test Tubes with Caps, 15-Pack

I bought them because they looked interesting. Not sure what I will end up using them for. They are very rugged so they will make excellent storage containers for lots of small items.

These are actually plastic 2 liter soda bottles that haven't been blown out into their final form. In this form, they seem to hold a maximum of about 50ml. Because it was made to be expanded, the plastic is actually fairly thick and seems pretty tough. The first thing I did with one was to put an emergency kit in the bottle and wound 50 feet of paracord around it. I'm still finding uses for all the ones I have left.

I bought these to make some more HOBO fishing rigs. You can store all your goodies inside. Lots of ideas online on how to make your own. Also perfect to use for waterproof first aid or survival kit! Best price anywhere on these!

Pre-Form Tube nice & very strong, holds 1.5oz/44ml of liquid except... 6.7% damaged 1 of 15 had the collar damaged, several reviews mention this since the broken piece was found in the bag this happened after probably due to ROUGH handling in warehouse or during shipping these things are a bit heavy, would not recommend for ultra-lite camping using for other projects, like a Fire Kit, 1/4" bit storage, or whatever

I use these for geocaching. They are great for keeping out moisture.

Just got them and WOW !! Just what I wanted. Heavy duty plastic and just right for what I need.

Love these durable test tubes. Hours of fun

my fermented juice holds pressure which is great saccharomyces boulardii

I've purchased these for geocaching containers before from another supplier. I was pleased that these were just as good as the last. Sturdy and the caps keep wet weather out. I've painted the caps with a spray paint, and they keep the paint well. Great for my purpose. I will buy them again.

Great little storage bottles, precisely as described

I order two packs of the 15 and 15 of the bottles were broken
