18pcs Glass Test Tubes with Cork Stoppers 25x120mm Flat Bottom | Clear Glass, Flat-Bottom Design, Cork Stoppers, for Plant Propagation Bath Salts Candy Storage Crafts and Experiments

Excellent quality, glass test tubes!. Corks do not have a tight seal though. I am using them in a plant propagation station and it is perfect. Arrived in great Styrofoam packaging. No cracks or breaks. The bottoms are flat vs rounded so they can stand up on their own if needed.

These are much nicer than I expected them to be for the price. I was looking for test tubes to make propagation stations. Many of the tubes on Amazon have reviews that they are cheap and thin, these ones are thicker. They’re plenty durable for what I’m using them for. I will order more in the future.

I highly encourage those who are looking at this product for propagation to just get them! They came packaged well and nothing broken. They stand well on their own, but can be very easy to knock over. However, none of them have broke and I’ve had them for maybe 2 months. Definitely glad I went ahead and bought them. My cuttings stand up nicely and they are putting out plenty of roots and even leaves between how sheer these are and my grow lights.

great value.

Fantastic! Really nice size! Using for propagations and tissue cultures

Not fair to ding the product for this, but thought it would be good info for others. I was looking to use these as a single dose coffee storage setup, but not big enough to hold 18g of whole bean coffee, would say it holds around 14-16g max. Otherwise would say the corks don't fit very tight, not sure if they would provide a good seal long term, work well enough to keep stuff from falling into the tubes. Otherwise I'm sure they would be fine for some sort of science experiment as they are meant to be used.

I use them for herbal pre-rolls at my store and th3y give the product and elegant aesthetic

They were packaged very well. I like that they have the flat bottoms. I wanted them for candle holders to propagate plants. They were a little too big in circumference for what I needed but that was my fault for not measuring properly, they were exactly what I was looking for.

Packaging was not good and 3 of the test tubes were smashed when I opened the wrapping. I also ordered these because I specifically need test tubes that have an outside diameter of 25mm (which is what the info for these says they are) but they’re wider than that. Outside diameter is about 30 mm. so they won’t even work for what I need them for.

Nothing broken all good

I absolutely love these! Came Well packaged inside foam, they are perfect for my bath salts! I will be ordering again soon.

Merci A+++++
