I have been looking around for some time for a decent paint rack that I could use to store my paints for easy access. To date I haven't had much luck. Then it hit me that perhaps either a spice rack or nail polish rack would fit the bill. Trolling eBay I came across these:
Its a nail paint wall rack make of wood and is available on eBay if you search around for it. It stands at over 70cm's in height, over 50 cm's in length and is 5cm's wide.
I get about sixteen Citadel paint bottles per shelf. So each rack holds around 96 paint bottles. As I bought two off eBay, that equals a total of 192 paint bottles. More that I currently have.
The price was around AUD$50 and they are solidly built. They come with hangers on the back to hang off a picture hook. I easily removed these as I wanted them flush against the wall at the back of my painting table.
What it won't hold can be seen below. The Tamiya paint bottle is just too wide to fit in the shelf and the other paints... well they speak for themselves.
Good buy and highly recommended.
