10Pcs Bubble Spirit Levels Mini Circular Bullseye Bubble Level Small Round Spirit Level Measuring Layout Tools (10x6mm, Non-Adhesive)

Almost need a magnifier to see

Cute little bubble balance, about 3/8 in diameter, maybe too small for my old eyes, they work

So tiny as to be useless . . . I’m posting this because I just don’t think people realize how small these are until they get them ~ please see pic . . . hope that helps.

I bought these with the idea of gluing them to drill and other tools where having a horizontal line is useful. These are small enough to fit on a hand drill motor, but too small to be very accurate. A bit better than toys, but useful in certain situations.

They work very well.

I wanted levels for my drill, so I made a bracket for it and added a bubble level for horizontal use and a tab for another level at the rear for vertical use. This level was perfect.There is no adhesive on these. I almost deducted a star for that, then thought I would rather add my own than possibly have it fall off due to a weak or old adhesive. Clear Gorilla glue worked fine.Hope this helps. Jim

Tiny bubble levels, perfect for a project

i get that a small bubble level is convenient, I even concede that these can be manually calibrated using some sandpaper and a trusted level, but what is the use case for a bubble level that has this level of non-precision? The lines are more than a degree apart, but there's no way to tell when the bubble is centered at 0 degrees. So this level tells you "somewhere between +1 and -1 degrees off.
