I will try some new pictures this morning.

The larger bead is slightly squared at 4.7 mm x 5.1mm

The other beads is more round but still has slightly flattened sides with a slight widening in the middle. So slight almost not noticeable.

The beads are approx 0,5 to 0.6mm. I used a broom bristle to check for the bump in the middle and it is almost the exact same thickness as the beads?? Very thin
