I had to share this info with you, with a link. This rack holds a 100 ink pads, and I have mine mounted on the wall at my work area. The price is a real deal for what you get, as it is so sturdy and mine is almost 10 yrs. old already. I recommend it highly and 2 of my stamping friends have also bought these same racks. I have no trouble storing my GkD inks, my Distress inks from Tim Holtz, and Memento inks - They all fit wonderfully.
You won't regret this purchase. If a few slots are a little too snug, you can sand the tops a smidgen, and since you can add the ink name on a little stick on label to the side edge , you can see their names at a glance.
Here is a picture of the rack from their web site, and it costs less than $25.00.
You will love this and I find it is more conveniently that stacking the inks in a drawer! Been there and done that --but it was years and years ago!
