It seems that each 6 drawer Helmer would hold 504 bottles of Zoya, so for the same price I paid, I could have had two, and stored 1008. Well, my collection isn't that big yet, and will take a while to get there. (I tend to only buy Zoya).
I went to Michael's yesterday and bought two of these. They were on sale for 30% off. Before sale I think they were $39.99. They are made by JetMax.
Putting them together was easy. You can just look at the pictures, no reading necessary. The material is of very good quality, it feels sturdy. (Just don't get over zealous with the screws, you could strip them.) All the holes align, all sides are finished. I used a Philips screw driver with two interchangeable sized heads. It took me an hour to assemble one. The second might go quicker.
Each drawer holds 110 bottles!! 330 for the whole thing! 660 for two! :,)
Toffee had to check things out. (I promise it's a square cube.)
( I swear, that's not some turd in the upper left corner...it's the end of the garden sprayer. I had watered my starter plants this morning.)
There is a gap to the side of the polishes, but it's not enough to fit another bottle without making a row bow out. You could put one on the side, offset from the rows, but with 110, it's heavy enough. Support the drawer with your hands when pulling it out very far.
