Simple, sturdy, and very versatile
I used these Mainstays cube storage H inserts to create more storage and they worked out great. They feel sturdy, are easy to position, and the white finish looks clean and modern. I don't have cube shelves, so I flipped the top inserts to create additional storage space and used them to organize handbags. It worked perfectly and made everything easier to see and access. Great option if you want a simple, affordable way to add structure and maximize storage. — @johannavargasrealtor

Love the extra shelving this provides!
These are great for adding additional shelving for your cube storage. If you've put together furniture before, then you won't have any trouble at all putting these together. I was able to do it without even looking at the directions. I love that it gives me additional shelving for shoes so that the shoes aren't sitting on top of each other. They fit in perfectly.

Perfect fit shelves
These inserts are just perfect for the mainstay cube shelf set. I have gotten that previously, and I like these shelves that just split up the space perfectly. They slide in perfectly, they're sturdy enough, and they are a nice snug fit. I use them to split up the space for shoes, which it works perfectly for.
