iroha koharu Spring Bud | For Your First Internal Experience — Slender, Gentle

Directing the Unease: A little fear, a little unease, but curiosity is quietly encouraging you.

This was the original intention behind the creation of iroha koharu Spring Bud—not to pursue intense orgasms, but to accompany you on a journey of self-pleasure. Most vibrators on the market emphasize "how strong, how fast, how fierce," but koharu is different. It is a product specifically designed for "first-timers" by the iroha development team after countless discussions.

Slender like a finger: Reducing the fear of insertion. Koharu is the most slender insertable product in iroha's entire range. The body diameter is only 22mm, thinner than your thumb. This is no coincidence, but rather the design team's insistence:

"We hope that even those who have never had an insertion experience will not feel pressured or uncomfortable." The tapered bud-shaped tip ensures that insertion doesn't feel like being "stretched open," but rather like a finger gently exploring—gentle, natural, and without fear. Bud-shaped: Flexible and conforming to the body. Why a bud? Because "an unopened flower bud" symbolizes finding one's own unique pleasure.

Koharu's head is flexible and can bend to conform to your body's curves. No need for force, no need to adjust the angle; just a light grip will help you find the most comfortable position. Even for external use, the rounded head provides a delicate sensation like a fingertip caress.

Stepless knob: From gentle to powerful, as you wish. Koharu has no complicated button combinations. There is a knob at the bottom: turn right → vibration starts; continue turning → vibration gradually intensifies. From gentle as a butterfly's flutter to powerful as a deep massage. There are no fixed settings; every intensity is your own personal speed.

Quiet, Waterproof, Dustproof: Your Secret. So quiet that even your bedmate won't hear it—koharu's low-noise motor ensures you don't have to worry about being discovered by roommates or family. Can be used during showers and baths—IPX7 waterproof design means it's fine up to 50cm underwater. Rinse directly with water after use for cleanliness and hygiene.

Dust-proof coating that resists dust—the surface is specially treated to feel silky smooth and not attract dust. Put it in a drawer or on your bedside table, and it's always clean when you pick it up.

Who is koharu suitable for? This product is designed for the following three types of people:

First, you who have never had an insertion experience but are a little curious—use koharu to practice the feeling of "being entered" and reduce the fear of sexual activity.

Second, you who have tried insertion but experienced pain—the 22mm slender body allows your body to gradually adapt, so you no longer fear pain.

Third, you who want a daily self-pleasure toy but don't want anything too stimulating—comfortable for external use, non-pressurizing for internal use, versatile.
