PenBBS 456 Vacuum Filler Fountain Pen Disassembly, Cleaning and Refilling

This is my first time disassembling my PenBBS 456 Vac-filler fountain pen for cleaning and refilling with a different ink. I decided to brave doing it live on-camera. I refill the pen with Diamine Sapphire Blue. Music: Concerto No. 3 in F major, Op. 8, RV 293, "L'autumno" (Autumn) by Antonio Vivaldi, in HD quality!
