During my last flight, I didn’t even keep the nib upright, and still didn’t have problems. I had multiple vacuum fill pens with me, including the VAC Mini and Pilot Custom 823, and none of them leaked.
Congrats! I’ve just finished journal writing with my 700VAC R and Iroshizuki ink! It’s my favorite travel pen, both because of the large ink capacity and significantly decreased chance of leakage during flights.
The problem with Amazon is that they sometimes just combine all of a single item, say the pilot metropolitan, from all sellers, including Amazon, together in one place in the warehouse. If some sellers send fakes and others genuine product, when you order, you can get a dud from a reputable seller and genuine product from the counterfeit seller.
Sorry about the long sentences!
There’s no gender in spoken mandarin. He, She, and it are the same. When written, there is gender. Many native Chinese speakers struggle with “he” and “she” in English.
Sorry, no, but I’m interested to hear about your experience when you get them! My understanding about Jinhao pens (I just ordered several 82s) is that your experience with the nibs may vary. But they are replaceable and can be smoothed out when needed.
