This site is closing and we will open the new site!

Hello Customers!

Our CST Team started as hallyusuperstore on eBay in February 2017 and has been selling various kpop goods for 5 years.
In fact, it has risen to the second-best seller among Korean sellers on eBay.
However, in January 2021, we were suspended from eBay for unknown reasons,
and we created a new web-site called and operated it successfully for a year and a half.

However, my-cst site based on wordpress – woocommerce had many shortcomings.
In fact, the site went down several times evert month with a huge number of errors and chronic problems.
Every time a problem arises, it takes a lot of time and effort to fix it.
In the end, 20-30% of yesterday’s transactions were all denied.
Now, we are reaching a point where many customers are still unable to buy what they want.

As a result, our company has made an important decision.
we decided to close the old problematic site and create a new one.
The new site is “” the original company name.
The new site is Shopify based with few glitches or errors.
It looks like it will take another 3-4 days to complete.

Still, you don’t need to worry about your old orders.
Existing orders will be shipped as scheduled.
Also, all inventory tems and your person login records will be moved to the new site.

However, your existing CST Royalty Points cannot be transferred from the existing site.
Old point holders can log in to the new site ( and tell us how many points to transfer when we open the new site.
Then we will match it and apply it to the new points.

We will now close all orders after this post.
You can no longer buy items on
But again, all your existing orders will be shipped. You don’t have to worry

See you soon at !
