Just a suggestion; if you want to fit zebra g perfectly, find a #6 wood drill bit. Its diameter is 5.95 mm. Put zebra g on the bits straight area and with a pliers squeeze them together. That will increase the zebra g diameter a bit and it will perfectly fit to jinhao, easily putting it in and out. The only problem i have now is there is a tiny gap betwwen the feeder end and the nib. Trying to handle it now. Broke 2 jinhao feeders so far with my testings, i have 2 more to try :)
