My inexpensive JinHao x750 fountain pens arrived while we were gone, ordered after seeing a YouTube video showing how to make these cheap pens into flex nib pens by switching out the regular nib with a Zebra G flex nib (sold in a 10-pack for under $10 at JetPens.com). The red JinHao x750 cost under $4; with the nib costing $1, that makes the modified pen under $5.00 -- and the flex is amazing! The pen also comes with a converter already in it, ready to fill with fountain pen ink.
I've tried Noodler's flex pens but have never been happy with the ink-filling systems. This one fills similar to a Lamy Safari pen and seems to hold a good amount of ink without leakage.
The gold pen, also a JinHao x750, cost a few dollars more because it said it came with a bent nib which I wanted to try out. Unfortunately, the seller sent the wrong item and it has a regular nib. I have been trying to work with them to get the bent nib that was supposed to come with it but nothing yet. The seller is apparently Chinese (though I bought it through Amazon) and communication has been spotty. If I can't get the correct nib, I'll put another of the flex nibs in it.
Yesterday we also bought a dwarf holly shrub to replace a photinia shrub that died in the heavy rains . . . then found out that Bill is apparently allergic to it. So if we trim it, I'll be the one handling the branches. (I prefer a natural growth anyway.) And a huge bag of potting soil --- now I'm off to re-pot a much-overgrown aloe vera plant.
