I chose the Sailor Four Seasons Yukitsubaki and it came with a medium-fine gold nib. The barrel is a lovely ivory colour with faint, pretty little pink dots on them - they are meant to imitate camellia flowers that bloom in the winter.
The nib is beautiful - you can see the lovely etching on it and it also writes pretty well too! Super smooth, no feedback and it glides easily on both expensive and cheap paper.
I've had it inked with a Sailor cartridge initially but then swiftly teamed it with J. Herbin's Rouille d'Ancre. Here is a writing sample (sorry about the image quality!):
Overall, a great pen with a lovely design, lightweight yet sturdy build and a brilliant nib. It's not the finest nib I have but it is still one that I like. I'm a sucker for a pretty pen and this is exactly what the Sailor Yukitsubaki is :)
