First released in 2015, the O-Tenga (a play on "o-nenga" meaning "New Year Gift") is a premium gift set is to celebrate special occasions such as the new year. It contains six premium onacup in a gift box designed with the beauty of "Osaka" in mind.
These are so limited, we were only able to get ten of these, and once they are gone, they are gone...
There are a few traditions surrounding the o-nenga: ・They are usually presented by hand when going to wish people a happy new year ・They were originally used as an offering to the Shintoist god of the near year "Toshigami" in prayer for a good harvest and placed on the shrine within the house ・They are usually given to people in a higher status than you, people who you respect/have taken care of you
Because these are only available in Asia, the text and instructions are in Japanese
