Miniature India Painting

These are miniture paintings, The two circular paintings are 2 inches, And the oval one is 2 x 1 3/8 inches, I am not sure of the age of them or if they are painted on bone or ivory or something else, I do know that they are not plastic, The dark wavy lines on the back of the painting that you see in two of the images come from the packaging that they were in, Each painting is hand painted, I am looking for more infomation on them, If you know anything about these painting's leave a comment, Thanks
