I must have been around 10 or 11, maybe slightly younger, when I bought a Platignum fountain pen with my pocket money. I don’t think it was my first and I doubt I would have been allowed to use it at school as they provided free pencils, plus dip pen shaped ballpoints to those in the final year who had passed the writing test (so everybody by the final term in theory). This calligraphy set will have come later, but I suspect I still bought it before I was 14 or 15, which in some respects was odd as I hated writing and my calligraphy (from mandatory art classes) was poor at best.
