Easy and Stylish Organization with Quad Inserts

I bought this set of quad inserts and loved how easy they were to assemble. I use them to place Funko pops, but you can use it as well for books, shoes, or anything else. They look nice and match everything because of the black color. They work really well for keeping things organized.

Inserts

Inserts are very sturdy, have some weight to them, and are easy to insert in the shelf. Inserts are smooth and are a warm walnut color, I love the color. Inserts do require assembly with a Phillips head screwdriver, which is not included. Directions are very easy to follow.

The clean white finish blends well with any room

Each insert breaks a single cube into four separate compartments, which is perfect for sorting smaller items like accessories, office supplies, or toys. The clean white finish blends well with any room, whether you're using it in a closet, home office, or living space. Installation took just a couple of minutes-no tools required-and the fit was snug and secure.
