Maker Introduction

Hello, supporters! This is the Ensure maker.

Hello, I am Choo Booyeon, running the brand Ensure!

First of all, I sincerely thank all the supporters who participated in Ensure's first funding and first encore.
The choices of each and every one of you came together to achieve great results.
Every step of the project was deeply meaningful to me. It was not just a project to sell short-sleeved shirts, but knowing there were people who resonated with my vision and attention to detail gave me great strength :)
This encore funding is not just a simple resale, but my way of giving back to the supporters who trusted and purchased from us.
As a maker, and as an individual, I put my sincerity into creating this.

To both new supporters and those returning again, I will strive to repay you with even better service and quality!

[ensure Ensure] means 'to guarantee', and 'Let’s provide customers with guaranteed quality products at the most reasonable prices' is the brand slogan under which we were founded.

We are currently operating a domestic unisex casual fashion brand, and the reason we have come to Wadiz under the name Ensure, as a popular brand, is!
It is to deliver to you, at a reasonable price, a very expensive fabric that is hard to find in Korea!!

After sampling countless fabrics every day, we encountered a fabric of a quality rarely found in Korea.
However, the concept did not match our existing brand, and it felt like such a waste to leave this great fabric unused. So, we thought it would be wonderful to share its unique advantages with many people, which is why we decided to introduce it through Wadiz.

To be honest,70-count jangyung cotton The fabric cost is more than three to four times that of regular cotton, so it is difficult to make a profit at this price structure... haha.
However, thanks to the support of many backers, we successfully completed our first project. To express our gratitude, after multiple discussions with the factory, we are able to offer it once again at the most reasonable price possible.A great encore price is now available for you!!

In line with the meaning of [ensure], we want to provide guaranteed quality and reasonable prices to as many customers as possible.[1% Jangyung Cotton Premium Short Sleeve] and let you experience it.
We will approach you as Ensure, with guaranteed quality, to build a good relationship with Wadiz customers. Thank you.

We sincerely wish you a safe and joyful year in 2026.
We hope your daily life becomes even more comfortable, and we will do our best so that Ensure can be of help, even in a small way, in your everyday life :)
