These vintage 1940s glass buttons are a lovely soft and gentle pale pink with a pearly shimmer.
They an off centre line down one side in a shiny paler pink.
They have an integral glass shank on the back.
I have them in 2 sizes and the colours are slightly different, I think, because of the greater surface area of glass

8mm - silvery pink

8mm - silvery pink on decorative card
1cm -  silvery pink
1.2cm - a more baby pink
They come on sheets of 24.
Would be delightful for baby clothes, dolls clothes, lingerie or, of course, blouses and dresses.
I found them in an old button warehouse.
