Pack of embellishments called 'Sparkletz' made by Buttons Galore & More. There are two colours to choose from in the extras shop, Aquamarine or Mermaid. Both are a mix up of sequins and flat back gem type tiny embellishments. You'll need glue to add these to your projects or you can create shaker pocket filler with them.
A half pack of each colour of these, (two colours mixed into one of the retail packets) is part of the May/June 2021 Embellishment kit so if you subscribe to this kit only order these if you'd like an extra pack of them in one colour.
