Vintage Box of 20 Reels of Sparkly Cotton and Metallic Strands Thread

I found several boxes of these threads in an old haberdashery warehouse I cleared in Malta years ago.
Everything else in the warehouse was dated from between the 1920s to the early 1960s There is no label on these boxes but "bunt" is printed on the side which is German for colourful - so probably made in Germany.
There are 20 spools in each box - lots of different colours as you can see.
The thread is cotton with a thin metallic thread would around it making it glimmer and shine and there is probably about 20 yards on each spool.
The thread is not that strong - if you pull it hard it breaks - so more for gentle embroidery than macrame !
