I've stood firmly against multi-pens in the past. I had my reasons--they were too big to hold comfortably, all the moving parts seemed ill-fitted or would rattle when writing, pieces might break, there was never enough of some of the ink colors, refills were hard to source, and I generally preferred to just carry a variety of writing tools with me rather than mess with those inconveniences of the multi-pen. But those were the multi-pens of yore, and the more recent models I've tried have grown on me. And then when Uni starts putting Ghibli characters on them, well. Then they become must-haves.

Uni Jetstream Multi Pen

The Uni Jetstream 4&1 Kiki's Delivery Service 4 Color 0.38 mm Ballpoint Multi Pen + 0.5 mm Pencil is by far the most multitudinous multi-pen I've tried. Black, red, blue, and green ink each have their own clicky tab, and then the clip, when pushed down, reveals a mechanical pencil. Underneath the finial cap hides an eraser. This is the writing tool equivalent of the Swiss army knife.

Despite its complexity, it is fairly well made, though it hasn't done away with all my multi-pen woes. The body is sturdy, and not as thick as one would think for all the refills it contains. The rubber grip does a lot to help the writing comfort level. And while the refills are small, they're filled with Uni's excellent ink--a ballpoint that feels and acts with the smoothness of a gel pen. Replacement refills (Uni XSR 80-38) are easily obtained at JetPens. The mechanical pencil works well also, though it's a little fiddly to depress the clip for more lead, and the eraser is miniscule. The clip feels like the weak point of the pen. It does rattle a bit, and its springiness (necessary for it's pencil-deploying function) detracts from its clip functionality. I do worry that it will get broken or jammed if I toss the pen in a backpack or pocket without some kind of case or padding--and having it in a case does defeat some of the always-readiness that is the main benefit to a multi-pen. But only time will tell on its durability, and so far all is well.

Uni Jetstream Multi Pen Writing

While it may be big and rattly, I've never felt so prepared for any writing situation. It has everything I need to carry for work, AND it has Gigi on it. I've used it more than I thought I would, and even contemplated a backup copy. It isn't inexpensive for a pen at $24.50, but it's not expensive for four pens and a pencil. Overall I'm very pleased with it.
