Red Colour No. 79A is not colored all the way to the loop, it has different surface.
Colours 20B and 78A have different surface.
The surface treatment of wax beads, so-called waxing, is created by immersing the beads in a bath. Thanks to this, the paint also gets into the hole, but it does not mean that it will clog it. If the hole is filled, it is enough to pierce it with, for example, a rivet or a needle.
Please note that the colour shade might not match the previous stock.
