150Pieces Brushed Nickel Pawn Type Magnetic Push pin, Refrigerator Magnet, Office Magnet, Dry Erase Board Magnetic Needle, whiteboard Magnet, Round Stainless Steel Magnet, 3x3mm 150 Pieces

I bought these tiny magnets to use in 3DPrinty's Brick Block Puzzle Box 3D print. They work great and really give a nice "snap" feeling to the puzzle motions. It's exactly the size I needed, but man are they tiny!! I have plenty left for other projects, but am happy with the purchase.

These are almost certainly smaller than you think. I drilled into the edge of 1/4" plywood to have these hold the lid on a small gift box. This worked well for this purpose. I did stack 2-3 in each corner to help increase the power a little. With that setup in each corner, these held up the entire giftbox with a load of around 3 pounds. I'd say that's pretty impressive for the size.

once again a seller that lies dia 2.7-2.8mm- height 2.3 mmlaser cut for 3mmx3mm got this crap in now ,I have to order from Apex.com to get the right size that's what I get for using Amazon

These are 3.1mm in diameter and 2.7mm long. That's an issue if you're expecting the advertised size (e.g. for a non-customizable 3D print). They are magnets, which I guess is worth 2 stars.

Strong magnets for their size and material. Work great as 3D print inserts
