Vintage Bakelite Bracelet

Set of 5 vintage Bakelite bracelets in butterscotch color. Purchased these over 35 years ago at an antiques shop. One of the methods recommended by collectors to check the authenticity of Bakelite is to use a Q tip to rub the item with baking soda, which should then result in a light yellow stain on the Q tip (as shown on the above pictures)
