Published
THE CAST has published a retailer-authored guide converting its listed customer service hours from Korea Standard Time to UTC. The guide is intended to help international K-beauty shoppers understand when the shop’s support operates.
The published schedule
The guide cites weekday support from 10:00 to 17:00 KST, with a 12:00–13:00 lunch break, and converts the working periods to 01:00–03:00 and 04:00–08:00 UTC. It states that the published hours were checked on November 12, 2026 and may change.
Holidays and inquiries
The retailer’s information says support is closed on weekends and public holidays. The guide advises checking the Korean calendar, local time-zone changes and the current support page, and identifies My Page > 1:1 Inquiries as a channel for questions and replies.
