These are bonus items from Ito En's Oi Ocha green tea, circa 2004. They were immediately put back into a plastic bag after opening and have been stored unused at home for a long time. There are no smokers or pets in the house, but please refrain from purchasing if you are concerned. Includes 4 Ochaken (Tea Dogs), one of which has an Oi Ocha PET bottle, so I think it might be a secret item. Also includes 2 Ochaneko (Tea Cats). I also have other Ochaken & Ochaneko series items, as well as Mugicha-ken (Barley Tea Dogs) for sale. Please take a look if you'd like! m(_ _)m Instant purchase OK. I will also be listing these on other sites, so there is a chance they may be removed suddenly. Thank you for your understanding.
