T-lab (Tirabo) is a Japanese brand that produces wooden toys, decorative items and stationery. Their cutest collection titled "Polepole Animals" features 41 animals that are individually hand craved, sanded and painted. If you like, you can learn about the process and the material used for making the tiny creatures on their "products" page (which is in Japanese, you'll need to translate it through Google translator) and view other adorable things.
These animals can be purchased online from a website Japan Wave. They ship internationally!
