I love the design but i will definitely replace with 0.7 or 1.0 tip. can i use refill (0.7 and 1.0) "uni-ball jetstream rt ballpoint pen refills"?

You cannot. This refill is smaller. The 0.7 and 1.0 refills that fit this pen are the Uni SXR-80-07 and the Uni SXR-80-10 and you can find them in black, blue, green and red.

Anyone know if this pen can be refilled with a better quality ink? I like the body but the actual ink/refill is not good. Please list refill options.

Is the 0.28 refill the only one this pen takes?

it appears to me that any skinny barrel type refill will fit

will this oil-based pen work well with thin paper? Tomeo River paper?

This pen works great on Tomoe River paper. It is very smooth writing.
