These are amazing! Not really a blank but a super popular item to advertise or sell at shows. 

Mermaid makeup bags. Brush the sequins up and down with your fingers to change the colours! We can't stop playing with them. They have a nice cotton/poly black lining on the inside and an adorable black velvet ribbon on the zipper pull.

They measure approx - 5.5 x 3.75 inches.
