LUSUP believes it does.

Prime Silk, chosen by the world's luxury maisons.

Craftsmanship by Japanese artisans.
And, for select models, the subtle glow of K18 gold.

Precisely because no one else can see it, we spare no effort, no time, and no commitment to authenticity.
That is luxury, as LUSUP sees it.
