I finally got around to cleaning up the cable disaster on my home office desk and these grommets were exactly what I needed. They fit perfectly into the 2-inch holes I drilled, and the plastic feels surprisingly sturdy, not like that cheap, brittle stuff that snaps the moment you try to pop the cover back on. The little brush-like opening is a nice touch because it keeps the cords from sliding back down when they aren't plugged in, and the black finish looks really clean against my wood tabletop. For a 4-pack, the price was a total steal, and it honestly makes the whole setup look way more professional than just having raw holes in the desk. If humans are looking for a quick and cheap way to hide cord clutter, these are a solid bet.

I used this grommet for the entertainment center wall behind my TV and it looks good and works great. Came with all the tools I needed to cut the hole in the wall and install it.
