5col Rugged Geocache Waterproof Storage Tubes - Clear/Plastic, 5-Pack

This is a high end product worth getting. So I put it to the test. I first put some tissue paper inside and put the lid on. Ran water over it, especially near the opening. It passed, the tissue was completely dry. So it's waterproof. I then took it outside, I threw it up like 20 feet and let land on a concrete drive way. I did this several times and the only result was a minor scratch. Next I threw it down on the driveway. The first throw was like half strength. The tube bounced back at me. No defect appears so I threw it again only this time with all my strength. It bounced like a football. That resulted in a scratch. No cracks or chipping. I then ran some more water over it again to test it. Same result, it's waterproof. This is a great product in terms durability. The cap can be exchanged with normal size 2 litter bottle cap as well. So that's a plus.

I use these for a variety of things. I like that they seal up nicely and are impervious to water getting in. They're great for storing matches and tinder for a small fire-making kit as well as hooks, line and sinkers for a small fishing kit to go in a survival kit. Perfect for a small sewing kit, keeping meds dry, and any other small item you want to protect from the elements. Great for building a survival or bug-out bag. These things are not fragile and can take a beating.

I use these for Geocaching. Used in the upright position with the cap at the top vertically they seem to be fairly watertight. That doesn’t prevent condensation from getting any of the cap if the cap is left loose

I am using these for geocaches that I'm hiding. It is my goal to make caches that are of high quality, low-maintenance and fun to find. I get annoyed at unmaintained caches or poorly done caches in pill bottles or film canisters, which break easily and are not always watertight. I am currently creating a series of winter-friendly caches that hang in trees for a quick grab. This is common in Europe, so I wanted to make my own series. They work well wrapped in camo tape and hung with a bent coat hanger. I brought a few of these "PET tubes" from Europe and then ordered these. The one thing I'm unhappy about is that the lids seem flimsy compared to the ones from Europe, so it seems they could break easily. It also seems like it's possible to overtighten. I thought I'd give this a test. I put paper inside and submerged the tubes in the bathtub. The paper stayed completely dry. I threw it out of the second floor window onto the driveway - barely a scratch. So I am counting on these to be good durable caches that don't turn into junk like some caches I find. As far as the lids go, I guess worst-case, the lids can be replaced with any soda bottle lid. For value - They seem a bit expensive, over $2 each, whereas the ones from Europe were only a euro each. However, after reading mixed reviews of preform tubes from other sellers, this one is the best choice, and I'd recommend. One more thing to add, they are not tinted grey like in the picture. They are clear. But that doesn't matter to me since I wrapped them in camo tape anyway.

Got exactly what I thought I paid for here. PROS: Tubes are solid, very strong plastic.I ordered these for a very specific cache I want to place and they needed to be absolutely watertight. I used my dishwasher/toilet paper test on them: I placed a small corner of a square of toilet paper in one and closed the lid securely. Kept it soaking in water for about 2 hours and then ran it through the dishwasher. After the dishwasher completed, I dried the outside off thoroughly and checked the paper. It was perfectly dry. CONS: While I haven't had any functional failure because of it (hence the 5 stars), the lids seem like they would be easy to over-torque and break the water-tight seal. If that happens, I will update this review but so far so good. Regards, Dan

I like these tubes because they are sturdy and weatherproof for storing items. I'm sure they would be good for geocaching, but they are also excellent storing for preppers and backpackers who need compact safe containers.

Now that I have it in my hands, it is a lot bulkier than I anticipated, even though I knew the dimension ahead of time. Of course, it is the robustness of this bottle that attracted me to it to begin with. The external size to content volume ratio will make it less efficient to pack into the one gallon plastic bag that the TSA check requires. The volume is about 40ml. I intend to use 2 bottles to carry almost 3 doses of liquid medicine. It is less bulky than a large fat bottle that the medicine came it. The slim bottle(s) will slip into my jacket pocket easily. My work requires me to have lots of face to face meetings. I drink a lot of coffee and that means coffee breath. I carry mouth wash with me. Again, the slim bottle makes it easy. AND ... airplane compression and decompression had made my original mouthwash bottle leaked. It made a mess. This cap will hold! 40ml is to much of shave lotion, after shave, shampoo, conditioner, & hair gel to bring on a business trip. I will be using containers half the size.

Super tough and durable. Perfect for medicines, salad dressing, small kits (fishing/sewing) or anything else you can dream up to fit in it. They are water proof and virtually crushproof with normal use. I tested one to see how much they can take. I weigh 180 lbs and I jumped on it with boots on and I couldn't break it. I will definitely buy more.

I bought this product for the purpose of storing emergency supply of medications, they are perfect!!!
