Uni SXR-7 Jetstream Ballpoint Pen Refill - 0.7 mm

I really love uni jetstream standard 0.7, but its refill is not available anywhere. So please update the refill stock, because I've to buy a new pen each time.

I havent used the refills yet. The problem is that i bought a pen and I wanted to ensure i could use it beyond the first refill, but i couldnt find the refill on Amazon where I bought the pen.. Next time I might buy the pens from Bumbo itself, the service was fast enough and the refills were secured wll in the box.
I couldnt give 5 stars since I havent used the refills..

Was craving for the pens so long thanks to bamboo stationary made it possible at so reasonable price but I insist please remove shipping charges like above 500 rs.
