This rose gold set is made of copper-based metal elements. They will take on a red/brown patina over time, this is completely normal.
The set includes 5 different markers, stored in a small matching metal box.
1 glass medallion marker 20mm with a hook.
1 16mm glass medallion marker with a medium ring.
1 small 12mm hook medallion.
1 x large ring flower pendant.
1 mother-of-pearl bead tassel and glass drop with large ring.
You can pass needles up to size 5mm in the small markers and 9mm in the large ones.
I recommend using the lighter ones for the finer needles.
This will make a very nice gift for a knitter.
The marker rings or "markers" are essential for following your knitting, identifying the different zones, locating the start of the round when knitting in the round.
The lightness of these rings will not hinder your knitting.
The rings are made in France by Made in Laine in small series.
