100PCS White Soft Plastic Screw Hole Cover Plugs, 3mm Waterproof Cap Plug for Holes

I got these to fill in the screw holes on my PC fans and it looks great. there's no longer any holes on my fan because it's filled in with these!

Ikea didn't sell the cover holes for AURDAL closet systems, but these ones work!Not 5 stars because you may need to glue them because they fall out if you rub against them. Looks way better than empty holes.

Perfect for ikea bookshelves if you’re like me and your brain can’t handle the holes

Was looking for something to fit in the Ikea Billy bookshelf holes - these are the perfect size and don't fall out. They are perfect with the white bookcase color.

These are much softer than I expected. Worked for what I needed.

Not 3mm. It's slightly larger when I measured with my caliper, and actually quite inconsistent. Very disappointed.

Well, I had trouble finding the right size for an Ikea Billy bookcase hole plug. I have tried this little plug and most have stayed in but every so often I find 2-3 have randomly fallen out. I just put them back in. I didn't want to glue them in because I may want to move my shelf.

These do fit the Billy bookcase from IKEA perfectly. They look far better than the open screw holes

Oh my gosh. I wish I had found these cover caps earlier!! I had bought some elsewhere and while they did the job, they were big. You can see the size difference in my photo. These ones are perfect for the Billy bookcase. I will be purchasing more and replacing with these cover caps. LOVE!!!

These fit perfectly into the holes for Billy bookcase. They aren’t flush so when you come close you can see the rounded top of the plug but from a few steps back it blends in.If these were flush it would be perfect but it gets 5 stars cause there’s nothing else easily available

We have Besta ikea shelfs that havw factory pre-made holes. These plugs fit tightly inside the holes, but the head is a bit thick, so it doesnt look as good as i expected. Otherwise good silocone quality plugs.
