This is a good range of Forstner bits for occasional use. Each bit is packaged in an individual box with no labeling on the individual boxes (shanks are labeled). I opened each box and marked the individual box MM, then I also looked for the fractional equivalent in the description and also marked each box that IE 25MM=1". I took about five random bits and drilled holes in the scraps of wood ...They met my requirements so I can't comment on long lasting sharpness.The individual boxes come in one big box, good luck putting them back together in the same box.It's like a puzzle.But I didn't need the shipping box anyway .
