Here is what the container looks like with the Stickles in the open areas. You might notice that some of my bottles are bigger than others. Those are Studio G that I got at Michaels.

In the bottom photo it shows that there is about a 2" gap between the "bottoms" of the bottles and the under side of the lid. Here is the option I mentioned above... You could cut a second 53 holes x 43 holes piece, and place it on top of the bottles. Then store plain glitter glue, loose glitter bottles, etc. in the open space.
