I found several boxes of these reels of gorgeous intense shimmering blue rayon floss thread in an old haberdashery warehouse I cleared.
Everything else in there dated from the 1930s to the early 1960s.
The colour on the box says "saxe" but it's more of an electric blue - heading towards turquoise..
It's extremely shiny and catches the light marvellously.
The floss is made of several strands tightly twisted together.
I've untwisted the strands a bit in the 2nd photo so you can see.
Each reel weighs 28g - 1 ounce, but I don't know the length as it doesn't say it on the box !
Each reel is wrapped in cellophane and the odd brown mark you can see in the photos is where the cellophane wrapper has been glued together !
I'm selling these either individually or for a whole box of 16 reels.
