Hands-on testing pending. What follows is verified reference data and manufacturer specification, marked as such.

What we verified. The reference B0074OH5DK designates this pack on all six Amazon stores we checked, confirmed on EAN.

The failure these prevent. Everyone irons over a pin eventually. With plastic heads the result is a melted bead welded to the sole plate, which then transfers to whatever you press next — usually the garment you had nearly finished. Glass heads make that impossible. It is the entire argument, and it is enough.

What to check on your own fabric. Push one pin through a scrap and hold it to the light. If you can see the hole afterwards, you need a finer pin — or clips, or basting. That test takes ten seconds and it is more useful than any specification.
