81PCS Cryo Tubes 2ml, Plastic Small vials with Screw caps Sample Tubes,PP Material ，with Silica Gel Gasket，Free from DNase, RNase, Human DNA

They're leak-proof and ideal for ink samples because they have a ring around them. I only had one issue with this product: the spaces are slightly too large for the vials, causing them to wobble a little more than I'd like; they won't tip over, but they can rest at an angle. This could be a problem if you need to fill them up to the brim with liquid. Aside from that, this was a nice, high-quality product with excellent leak resistance. Proof seals that will work well with my fountain pen ink samples and allow me to dip my pen into them.

I've been receiving ink samples for my fountain pens, and I've been struggling to keep the 4ml vials contained without simply throwing them in a ziploc bag. The empty vials are handy for sharing ink with friends or taking small amounts of ink with me on the go, and the box these vials come in is perfect (the vials it comes with are the same size and shape as the standard ones I've gotten from all the companies I've gotten ink samples from), and the vials are the same size and shape as the standard ones I've gotten from all the companies I've gotten ink samples from.

The vials are wonderful. These were purchased for camping and hunting to store spices and other small quantities/use items. I needed something that would hold spices without making the rest of my kit smell like them, and that would not skip the threads and come loose if I cranked the lid down very tight. I'm very pleased.

I purchased this in order to test a variety of eliquid recipes in a cost-effective and well-organized manner. It performs admirably, but the following factors contributed to my decision to give it four stars: br>br>The case lid is a bit inconvenient and easily removed. A hinge with a latch, in my opinion, is preferable. br>br>The bottoms of the vials have a cone shape pressed into them. I'd prefer a flat bottom. br>br>Labels and markings are easily faded. The mold left a dimple on the lid. I considered getting small circular stickers to put on top, but I didn't want to wait to get started (so I used a sharpie - see below). It's a difficult task). br>br>Apart from that, it's a fantastic product at a reasonable price!.

Perfect for my purposes of using gibberellic acid to treat perennial seeds that are difficult to germinate. They can withstand water. The box is sturdy, and the lid fits perfectly. Because one of the corners is angled, the lid can only be applied in one direction. It is not possible to rotate it.

All of the items were of good quality and functioned properly. There were no missing gaskets, and all of them were of good quality.

I didn't need the caps because I bought it for plant propagation. It keeps everything in order. For me, it's perfect. Thank you very much!.
