What fragrances are in the set?

Amber Nuit, Sublime Oudh, Elegance and Sweet Amber, each a 30ml spray.

Is this a good way to try oudh?

Yes. Sublime Oudh gives a woody agarwood scent with cinnamon and labdanum up top and vanilla, amber and musk at the base, so you can test oudh without a full bottle.

Which scent is the most floral?

Elegance: bergamot, candied fruits and rose over jasmine and white flowers, finishing on musk, sandalwood and moss.

Which is the warmest, sweetest option?

Sweet Amber, built on cedar, sandalwood, patchouli, vetiver, guaiac wood and agar wood with jasmine and rose in the middle.

The four sprays come in a gift box, so it can be given as is.

Are these eau de parfum or eau de toilette?

The set is described as fragrances with musk, amber and oudh notes; concentration is not stated, so expect moderate wear rather than all-day projection.
