Every item is authentic. Guaranteed.
MUSTIT GLOBAL is operated by MUST IT, Korea's leading online luxury marketplace since 2011. We sell authentic products only — and we stand behind every item with a full-refund guarantee.
How we protect authenticity
- Verified sellers only — every product is sourced exclusively from sellers vetted and continuously monitored by MUST IT. Unverified or anonymous sellers cannot list on our platform.
- Hub inspection in Seoul — before any international dispatch, each item is received at the MUST IT hub in Seoul and checked for authenticity and condition.
- Professional appraisal — authentication is backed by professional luxury appraisal institutions designated by MUST IT.
- Zero tolerance — any seller found to list a counterfeit item faces legal action and a permanent ban from the platform.
Our guarantee
If an item you purchased is ever confirmed counterfeit, you receive a full refund and we cover every cost, including all shipping in both directions. Authentication is determined by our designated professional appraisal institutions, so you never need to obtain or pay for a local appraisal.
