Nicely marked with their sizes. And the sizes are quite accurate, and quite consistent. I measured each tip.
I measured them using gauge pins, checking which size pin would go through the hole, and which size would not. The pins come in 0.001" increments, letting you determine that the hole is bigger than XX (that pin fits through), and smaller than YY (that pin won't fit). I converted the inch pin sizes to metric.
0.2mm: Could not check. 0.3mm: between 0.31 and 0.33 0.4mm: between 0.38 and 0.43 (actually probably a closer range than this, but I was missing a gauge pin size) 0.5mm: between 0.48 and 0.51 0.6mm: between 0.58 and 0.61 0.8mm: between 0.76 and 0.79 1.0mm: between 0.99 and 1.00
