Reported longevity for the authentic MCM Onyx is split — one detailed reviewer measured about 4.5 hours before the scent dropped to skin level (weak for an EdP), while other buyers and retailer copy claim 6–8 hours; this is evidence for the genuine ONYX line only and cannot be assumed for this Guangxi-origin, non-imported unit.

This 100ml black backpack-bottle fragrance lists a floral, clove-forward profile with 18–25% fragrance oil for daily unisex wear. Written buyer evidence for this listing is absent, and the listed scent does not match community descriptions of the authentic ONYX. Confirm the scent profile and origin with the seller before ordering.

Pros
- · Backpack-shaped flacon is the feature genuine-bottle reviewers praise most, including some who were unimpressed by the juice.
- · Listed at 100ml with 18–25% fragrance oil and marked for women, men, and general daily wear.
- · Listed three-year shelf life; the only noted buyer comment on the sibling listing was that the dry-down smells good.
Cons
- · The listing's floral/clove description doesn't match community write-ups of the authentic MCM Onyx (grapefruit, ginger, pink pepper, lavender, basil, vetiver, tonka).
- · Written buyer feedback for this listing isn't available: the sibling Weidian page shows 93 reviews, 84 of them system defaults with no text or photos.
- · Origin is listed as Guangxi and marked non-imported, while genuine bottles are made in Italy — the origin difference is one of the markers MCM fragrance authenticators flag.
Fit notes
One size listed: 100ml, normal spec, 18–25% fragrance oil. Colour choices appear as code numbers (151353#, 151018#, 151209#, 152152#, 151100#) alongside a note to contact the seller.
Buy if
You want the backpack-shaped flacon — the detail reviewers of the genuine MCM bottle praise most — and can treat the scent itself as an open question. A 100ml daily-wear bottle for women or men fits.
Skip if
You need a documented scent or verified performance before buying. The listed floral/clove notes conflict with community descriptions of the authentic MCM Onyx, and no written buyer feedback exists for this listing.

Buying FAQ
Common questions
What does this fragrance smell like?⌄
The listing says floral with clove. That conflicts with community reviews of the authentic MCM Onyx, which describe a fresh-spicy woody fougère, so treat the listed scent profile as unverified.
How long does it last?⌄
Reported longevity for the genuine Onyx is split, with one detailed reviewer measuring about 4.5 hours and others claiming 6–8. That evidence covers the authentic line only and can't be assumed for this Guangxi-origin, non-imported unit.
Is the bottle shape a sign of quality?⌄
No. Reviewers of the genuine bottle call the Stark-backpack flacon and box the standout feature even when unimpressed by the scent, so bottle appearance isn't a reliable indicator of juice quality.
Is it unisex?⌄
Yes — the listing marks it for women, men, and general use, in a 100ml normal spec with a listed three-year shelf life.
What should I check before ordering?⌄
Confirm the scent profile and origin with the seller, and specify the colour code you want. MCM fragrance authenticator guidance also suggests checking bottle weight, loose or rattly metal details, and whether the scent fades within roughly 30–60 minutes.
Evidence
Public notes used
Text-based buyer feedback for this MCM backpack-bottle fragrance line on Weidian is very sparse: the most visible review page for a sibling listing shows 93 reviews, of which 84 are system default positives with no written content and no buyer photos, so this listing's own buyer sentiment cannot be independently verified.
SourceLine-level buyer evidence from a sibling Weidian listing for the same MCM black backpack-bottle fragrance (variant shown as 30ml, itemId 7408068832) is lukewarm: the reviewer said the mini-backpack bottle shape is distinctive but could not describe the scent, only that the dry-down smells good.
SourceCommunity reviewers of the genuine MCM Onyx — the 'ONYX' black backpack-bottle fragrance this listing's box imitates — consistently describe the juice as a fresh-spicy woody fougère (grapefruit, ginger, pink pepper, lavender, basil, vetiver, tonka) that reads as a Dior Sauvage relative, with some calling it synthetic or derivative; this does not match the listing's 'floral / clove' scent description, so the listed scent profile should be treated as unverified.
SourceThe bottle concept this listing copies is the aspect buyers of the genuine item praise most: reviewers repeatedly call the Stark-backpack-shaped flacon and box presentation the standout feature ('nothing short of incredible', 'cool bottle'), even when they are unimpressed by the scent — so bottle appearance is not a reliable indicator of juice quality here.
SourceGuidance from perfume buyers/authenticators for spotting fake MCM fragrance is relevant to this listing (Guangxi origin, listed as non-imported, versus the genuine bottles made in Italy): counterfeit MCM bottles feel lighter with loose, rattly metal details, the scent is one-dimensional rather than layered, and it typically fades within roughly 30–60 minutes, with sellers masking fakes behind terms like 原单/尾单 or 'cheap price'.
