Thank you for viewing! I've attached beads to wool felt. The wool felt is attached to the pin base with strong adhesive. Size: Round part: Approximately 1.5 cm Pin length: Approximately 5 cm As this is a handmade item, there may be some slight imperfections or misalignments. If you like it, please consider purchasing it. Thank you! m(__)m #handmade #woolfelt #beads #hairpin #hairaccessories
