It was almost impossible to find a fountain pen made in Vietnam. I did manage to find one called the Diem 70. I check out a some of cafes while on my search, and really get caffeinated up. Cafes include: The Cafe Apartments with Boo Cafe, Hanoi Day, OrienTea, Thinker & Dreamer, Saigon Oi and ParTea. Du Mien Garden Cafe. Villa Royale Downtown. Trung Nguyen Legend. The Work Shop. I also managed to find a fountain pen ink made in Vietnam and get it all over the place!
