I am a very deliberate buyer — more experience with fountain pens — and I usually ask myself if I will be truly “sad” if I miss out on a purchase. Actually thinking through that right now with a vintage, but apparently NOS Cartier pen in Europe. It would help if i could see the pen (box and papers) in person plus I am a bit concerned about shipping delays or losses during this pandemic. Anyway, point well taken, Nicolas, about being decisive or missing out!
