Review: It works - I did not have assembly issues like others complained about. Shelves are snug and there were no burrs interfering with assembly. End plates will flex out of alignment when trying to slide in shelves, but just be careful and there should be no issues. W just a little care, No reason to break! Individual pieces are strong enough that I would not worry about breakage unless handled negligently. I was a manufacturing engineer for 25+ years and I would say these are good quality design, materials and fabrication. I approve! As you can see in the pictures, I am using it to hold 5ML cryo sample vials. My vials are short and hang by the cap when rack is assembled as intended. This is great for storage in the freezer. When filling and using vials, I can swap the bottom and center plates and use the rack right-side up or upside-down depending on how tall I want the vials sticking up above the top of the rack. I prefer up-side down. it holds the vials a little more securely. The vials can be stood upright or held in the rack in a back leaning angle to facilitate reading of any labels. FYI - My vials are 16mm vials and I was concerned the fit might be tight; especially with the raised volume indicator marks on the outside of the vials. But clearance is perfect. Good purchase and you can't beat the price.
Review: Perfect for fountain pen ink samples! - I bought the 15/18mm (pack of 2) to store my fountain pen ink samples. It is PERFECT! It comes disassembled, flat, and assembling it is not difficult. It is sturdy enough (compared to another one I had in the past) and the size is just right. I'm even happier since the listing says 40 holes, and I got the 50 hole version - even better!!! I nearly spent double for the Karter brand (which is the current bestseller) but really there was no need, this one is EXACTLY what I wanted. :-)

### ⭐⭐⭐⭐⭐ Cheap handy little tool that does what it advertises.
*by J***S on March 21, 2025*

Firstly, the poor reviews and the correct information: 1-Yes it is cheap and yes is challenging to put together but once done it’s a fine item. 2-Yes you CAN return it. 3-Yes it does what it is supposed to do. I don’t do reviews unless I find enough incorrect information to provide correction. I used this for desktop ink pens and it works fine. Two of my negative remarks: it does not fit pens with clips on the side which have to be placed upside down to fit and there is no bottom so pens fall out when the unit is moved or lifted. That’s it for a cheap handy little tool that does what it advertises.
