This was another item that finally showed up on Yahoo Japan that I didn't even know I was waiting on. I won it cheaply and received it brand new in the package! This series looks to be early Diamond and Pearl release from 2006.
Thick Plastic Pokemon Center Keychain
Source: Yahoo! Japan
This keychain was a cheap (100 yen?) find on Yahoo Japan, and I was pleasantly surprised by how nicely made it is - it's very thick and has a nice feel to it. I'd definitely use it on my keychain if it weren't so rare! It's a 2007 promotion item (you can tell by the copyright), but I'd never seen one before this.
You can see the back of the keychain here.
Spinning Keychain

That white bit on the left side is a Master Ball - pull it and let go, and the Dialga spins!

Pokemon Center Rubber Name Keychain

Declare that name loud and proud, Dialga! I like the unique design on this one. I'd actually never seen it before until this one appeared, and I search for Dialga nearly every day, so it must be either rare or new!

Chara Metal Collection Charms
Source: Yahoo! Japan
I love these charms. They're about 1" across, shaped to fit the Dialga, and lightly engraved with the Pokemon movie's logo on the back. The silver charm on the left is the normal 10th Movie version, the gold one on the right is the 'secret' rarer version (also from the 10th movie), and the one on the bottom is the 12th movie version.
I bought 2 boxes of the 10th movie charms to ensure that I got a Dialga (even before I knew there were 2 versions of him), and still have at least
one left of every Pokemon in the set! Oy.

Reflective Keychain

This reflective (and very large) keychain can be worn at night for increased safety. Neat!

'Flowing' Tube Keychain

This keychain has a little bit of water (or something) inside so that a picture of Dialga floats back and forth from one side to the other.

Part of a small collection of items featuring the Game Boy and DS games.

10th and 12th Movies Enameled Keychains

Both of these are from sets of 6, sold as movie promotional items (in the theater and at the Pokemon Center). There's both an A set and B set, each with three Pokemon on it. I found the older one on YJ, and grabbed two of the new sets during the 2009 promotion.

(11th Movie) Dog Tag

This dog tag has spots on the back to write your name and blood type, the two most important parts of your personality.

Miniature Pendant

This pendant is part of a larger charm set, that has Palkia and the three evolved Sinnoh starters. I thought it would be easier to separate from the rest of them, but it would actually require bending the chain...so I am leaving it as is for now ^_^;

Cut-out Lens Cleaner

A nifty cleaner that seems a little less likely to scratch a screen than the figure versions. I sometimes clean my laptop screen with this one.
Security Buzzer Keychain

Why is this one still in the package? Well, this is a security buzzer for children to pull when they feel threatened, that puts out a BIG noise. So it's like a car alarm for your kid!
Given the nature of car alarms, I'm keeping this in the package so it doesn't go off by accident.
Digital Clock Keychains

Nifty watch keychains in 2 different colors. Since I have 2 I often wear the second one, which is why it's so beat up.

Enameled Plastic Keychain

This plastic keychain is big and has nice colors. I'd use it, but I don't want to get it all dented up. It's similar looking to the rubber keychain ToysnJoys has, which I also want, but I don't want to place an order if they might never send it. So, somewhere else, I hope.

A tiny, flat and shiny keychain with a little bell Master Ball.

Pokedoll
Phone Strap Charm

It's really hard to find Dialga stuff where it's in its Pokedoll form, but I found this phone strap! It's very tiny and very cute. This is a gachapon item from the 10th movie promotion.

I got really excited about these when ridi linked an image of one of these she'd bought for someone else, and she kindly picked one up for me at the Pokemon Center when she was in Japan. Thank you!

Series Keychain

I had to buy about 12 boxes of these before I got Dialga, and even then I sold off the PorygonZ half. But it's ok, I got a new keychain!
