Does what I needed it to do
Size: 50mm/2inch, Color: Black, Number of Items: 4
Worked perfectly for routing all my wires for my desk. The included tie straps were an added bonus. Now everything is nice, tidy and secured to the back side of my rolling desk.

Great to clean up the cable clutter
Size: 50mm/2inch, Color: Black, Number of Items: 4
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.
