Eowpower 50 Pieces 5 ml Plastic Sample Bottle Vial Storage Container for Laboratory Lab

I use these to send ink samples to my friends. They hold liquids perfectly and I’ve had no issues with leaking even during shipping. These are great quality and i highly recommend.

These are very affordable. I made samples for a friend and none leaked in shipment. Using them at home to store small amounts of bottled inks, so I don't dip dirty pens in bottles and introduce microbes. Hopefully this will keep my ink bottles mold-free. Also useful for storing small amounts of mixed ink. These are surprisingly useful, I've nearly used up my first 100!

They appear to be good quality, I like the screw caps, and the seal ring to help prevent spills. I purchased these for fountain ink samples and mixing. The only reason for the loss of a star is because it is supposed to be a pack of 50. There are 51 vials... but only 49 caps. If you purchased this and needed all 50 to be functional you would be disappointed.

I got these to send ink samples to a friend who has taken up fountain pens as a hobby. I was sending them to australia (from the US) and needed something that was water proof, and would hold up to what I can imagine will be some abuses during the journey (tossing onto and off of trucks and airplanes during the journey). The package got returned to me (TX) from (TN) due to them wanting more info on what was inside. I provided that info, they returned it to me anyway. No leaks. I reshipped the package having provided the additional info re: contents. The package was returned to me (TX) from (TN) because I put the value at 0.00 since it was a gift. I, again, re-valued the gift at 0.01 and shipped again, no leaks. It's SAYING it will arrive monday. I have zero faith that it actually will, but the important part... No visible leaks and it's been to tennessee from texas TWICE already... Let's hear it for our ever vigilant shipping partners, and whomever came up with the seal caps on these vials.... =)

They do their job, seem to be good quality, and you get a lot for the money. Probably more than you need haha. They should also sell a smaller quantity for a lower price, because I didn't need 50 of these.

Great for fountain pen ink sample storage. Value for money compared to 3 times the price on goulet. I got a tube holder that holds all these. Great option.

Perfect. Mine came with built in gaskets so leak proof!

I've used glass bottles but the lids never really held the liquid, once I got these with the little rubber ring, the liquid stays in and they don't leak. Perfect for my project!
