Developed in Collaboration With Kiko Mizuhara, the iroha koharu SUIREN
For this collaborative project, we worked with Kiko in development of the iroha koharu, an item that has been talked about in previous development discussions.
What is the iroha koharu?
iroha koharu is a slim and compact insertable item. It's the most slender iroha item, so it's also recommended for beginners to self-pleasure.
This is an item that was made to address the various concerns and feelings people have towards self-pleasure and insertion.
iroha koharu is an item designed in the shape of a flower bud.
The product reminded Kiko of a water lily, so this time, she decided on the iroha koharu SUIREN (water lily in Japanese) for the next collaboration item.
In Japanese flower language the water lily means "trust". The color of the iroha koharu BENI is light pink, and the color of HINA is gentle yellow, so the pastel purple tones complement the existing iroha koharu range.
Choosing the Color of the iroha koharu SUIREN
There are many different types of water lilies, including white, pink, and purple.
The first step is to decide on the color by comparing the prototypes of the iroha koharu that match the color of each water lily.
Kiko worked with the product developers to find the right combination of colors for the top and bottom parts of the product.
While looking at all the options, Kiko picked up the purple color and said, "This is a beautiful combination..."
Considering how it will look next to the existing koharu products, the purple color that was chosen is perfect! And so the color was decided.
Checking Out the Prototypes
Finally a prototype of the purple colored iroha koharu was completed!
Later on, Kiko personally checked the color.
"Beautiful! It's pretty! This pale, pastel color. I want it now!" (Kiko Mizuhara)
Kiko also highly praised the original koharu colors.
It's also well balanced and cute when you see it side by side with the iroha koharu you already have!
The iroha koharu Series is now even brighter and more gorgeously colorful.
Finally, it is time to consider the package that will be the first thing people see. This includes checking the overall color and attached stickers.
iroha koharu SUIREN is Complete
Later on, we handed the completed iroha koharu SUIREN to Kiko.
"Wow, it's exquisite! And what a beautiful color! I'm looking forward to the launch!" (Kiko Mizuhara)
Kiko expressed her joy as the completed collaboration item was exactly as she imagined.
A sticker with a photograph of Kiko Mizuhara is affixed to each iroha koharu SUIREN.
And in this way, the iroha koharu SUIREN is ready. We would be overjoyed if as many people as possible enjoy it!
