From Yahoo Japan Auctions via my proxy, Goody Japan. Sets 1 & 2 from the first anime series in 2004-2005. These were surprisingly cheap (I think the first set was only 500yen) and they're all really well-made. The coloring on the first set has a little too deep of flesh tone, but other than that they're both really cool gashapon sets.
From Yahoo Japan Auctions via my proxy, Goody Japan. Looks more like an otter than a cat, to me, but still really cute, nonetheless! The dorobo (thief) scarf tied around his head is super-cute as well! The straps are from the same series, and unlike most series like this, the quality didn't really change from the larger one, they look similar and they're made similarly. Very nice, overall.
More recent acquisitions from Goody-Japan's YHJA proxy bidding service. Got a lot of little Kyoro-chans from a recycle shop's auctions. A good deal, nearly all you see in the first image for only 1000 yen! Most are straps that had like animal "outfits" on or whatever, I pulled the doubles out of their suits so I could have an army of little Kyoros on my shelves.
I also (finally) got some Tohato mascot items. I love their products and their mascots (especially Bakkun, the Habanero Snack mascot), and I knew that they made plushes based on their mascot chara, but I had no idea that they had nifty little Gashapon until I just searched YHJA for the very basic, 'Tohato' and 'habanero', respectively. The straps that look rectangular are meant to be bags filled with little plastic "snacks" that you can see if you look in the back. (I couldn't get a good shot of them) The ones that look like cartons pull up in the center, and reveal a chain of snacks looped by a rubberband/nylon cord. Especially neat are the Habanero Snack and Biscuit Snack keychains, as they have a tiny version of their mascot inside, peeking out over the top of the bag/carton thingy.
