Daum France crystal MCM retailer pen holder

Unique clear crystal pen holder signed Daum France. Having the original pen( not working).The crystal retailer piece is 7 3/4” and the pen is 8 1/2”, slightly taller. The pen holder is adjustable and has a gold finish. The metal piece is mounted in the crystal. There is no damage or chips. It is signed Daum France. I am guessing on the age based on the pen design. It looks like an early ball point pen.
