Thanks everyone! I assume it is refillable and reusable.

Many thanks for your answer.
Looking forward to acquire my first Mitchell.

Hello, I have found a spare spool that I believe comes from a Mitchell reel. As I would love to buy the reel, I would like to know the model. Unfortunately no information comes from the spool itself apart from 'made in France' and right/droiter on the top. Many thanks, https://onedrive.live.com/embe...
