Lot of 16 Purple Hibiscus Flowers on Shiny Mother of Pearl Buttons, 3 sizes, Outlet Item, $10.00, # MV25

The image is a little hard to see because the flower image isn't quite sharp enough, and the top clear coat, perhaps acrylic resin, is so shiny that the details get a little lost. That's why they're an Outlet Item. They're unique and interesting; the hibiscus print has been mounted on to natural shank-back Mother of Pearl buttons, sleek, smooth and shiny, some with a bit of a curve. You'll get all 16 for $10.00. Order "1" for this set. 

Three are 1-1/8", five are 7/8", eight are 3/4".  Age and where made is unknown; possibly vintage.
