[Background and Vision Behind Surpassing 2,000 New Customers]
Whitening Cafe Sendai has received many "dental concerns" to date.
"Other salons didn't show results," "I gave up at the dental clinic because of the pain," "I want to change myself, starting with a student discount."
The number 2,000 is proof that we have faced and resolved the concerns of each individual. Now, with a new system in place after a change in store manager, we are once again strengthening our "community-based approach" and will continue to focus on services, prices, and results unique to the Sendai store, setting us apart from other branches.
【Our Dream (April Dream)】
"To make Sendai, the City of Trees, the city with the world's brightest smiles."
Our dream goes beyond the scope of a mere beauty salon; it is to make teeth whitening a "new normal" in Sendai.
Students striving for job hunting, couples anticipating important anniversaries, business professionals who never forget self-improvement. We aim to create a society where all Sendai citizens can live positively every day, armed with the "confidence" they can gain in as little as 30 minutes.
Confidence in the smiles of everyone in Sendai
[Details of the 2,000 Customer Milestone Commemorative Thanksgiving Festival]
As a first step towards this dream, we are implementing the following special campaign starting today.
"Why do we, with our proven track record, continue to offer this price?"
While price competition is intensifying in Sendai City, we believe that what is important in self-whitening is not "cheapness" itself, but "the ability to safely and reliably experience true whiteness."
Our setting the initial 32-minute irradiation at 2,480 yen is by no means for the purpose of selling cheaply. It is a manifestation of our determination as a community-based store, wishing that those who "seriously want to whiten their teeth" do not compromise or fail at the first step.
The technical expertise cultivated through operating over 50 stores nationwide, a track record of over 2,000 treatments, and the trust from third parties through 23 media features. This special price is for you to first correctly experience the "high-quality whitening" that condenses all of these.
Those who only seek "one-time cheapness" may not be satisfied. However, for those who "seriously want to achieve a sense of cleanliness and change themselves," we promise that our store is the best partner in Sendai.
