Reddit mentions of Uni Writing neatly Mechanical Pencil, Lime Green, 0.5mm (M5-5591P.5)

Tombow Olno: Extend lead by bending the pencil in any direction.

Tombow Mono Graph: Shaker with phat eraser.

Pilot Mogulair: Shaker with a suspension that prevents lead breakage. Not as fool-proof as the DelGuard, but it's pretty good actually, and it is a better pencil overall in my opinion in terms of grip, looks, and overall quality.

Pentel Orenz: Pentel Excellence with a sliding sleeve so good you can write with 0.2mm without breakage.

Kuru Toga Advance or Pipe Slide: Twice the rotation speed for a sharper line and a sliding sleeve.

Pilot Dr. Grip: Shaker with great grip.

Pilot Fure Fure Super Grip: Shaker with sliding sleeve in an amazing neon orange body.

Pilot Automac: All metal, automatic pencil with a retractable tip. The lead automagically extends as you write.

Platinum OLEeNU Shield: Double clutch let's you use more of your lead, and a small suspension helps prevent lead breakage. The retractable lead sleeve is supposed to be a sliding sleeve, but it's not really, and the mechanism is iffy. The only reason I recommend this one is because it's comfortable, the clip is tough, and it's really cheap ($3.30) so you can use it to get a JetPens order to $25 for free shipping.

I was on the same quest as you, so I own all of these and personally recommend them.

Nope, never mind. The Amazon ones aren't actually sold by Amazon, and so don't have international shipping. And while Rakuten does vary from shop to shop, I was expecting at least one of them to mention EMS but, well. :/

Sorry for getting your hopes up. If you really want the pencils, you can probably use a forwarding service or something.

Here is what I saw but clearly didn't look closely enough at:

Amazon: Blue Red Navy Black White Green

Rakuten: Shop Shop Shop Shop Shop
