This is a fair price for the item received. I didn't get a whole nozzle of 0.10mm because somewhere along the way part of the drill bit broke off. It's a very tiny bit and I wasn't planning on using it anyway. Based on the photos in the listing I would guess it would only be 1-2mm long, but that part is missing from the brown-collared bat in my photo. Haven't used this in CNC yet as I hand drill with a pin vise. The cutting is aggressive and gets the job done, but these are tiny parts and break easily. I removed the top of one, with accidental side loading. All my fault. I straightened the tip a bit and it still cuts fine.
