At a glance
Louis Vuitton's Alma BB Monogram M46990 is listed at 23.5 × 17.5 × 11.5 cm in length × height × width order. It has a double-zip closure, two Toron handles and a removable adjustable strap with a 50–62 cm drop. The body is Monogram coated canvas with natural cowhide trim, so describing this version as entirely leather would be inaccurate.
Identify Monogram M46990 before comparing dimensions
The official Singapore page gives the M46990 measurements as 23.5 cm length, 17.5 cm height and 11.5 cm width, plus a weight of 0.5 kg. Preserve that stated order rather than moving the numbers into a different axis convention. Other Alma materials or editions need their own specifications.
Louis Vuitton describes the design as tracing back to an Art Deco original from 1934. That historical reference is not evidence that the present M46990 Alma BB version was launched in 1934. This guide concerns the checked current reference and its listed details, not a new-release announcement.

A domed body changes the fit question
The Alma BB's rounded top is visible in both the official design and the separate supplier photograph. Exterior length at the wider part of the body does not guarantee equal clearance near the top. A rigid rectangular item needs to pass through the opening and sit below the curved shoulders.
The official specification lists a double-zip closure, padlock and key bell. Ask for a photograph with both zip pulls moved open when assessing a supplier item. This reveals the access path more clearly than a closed front view; it still does not replace an internal measurement or a packing demonstration.

Separate the canvas body from leather trim
For M46990, Louis Vuitton lists Monogram coated canvas, natural cowhide leather trim and textile lining. Its details also include gold-colour hardware, an inside flat pocket and four protective metal studs on the bottom. These components have different roles and should not be collapsed into one all-leather description.
The linked supplier SKU KU-B46A4448 is recorded as canvas, based on its supplier description. That field does not independently establish the official coating, cowhide trim or textile lining. Request the body, handle, trim and lining materials separately if their construction or care requirements affect your decision.

Check strap drop and the brand's packing example
The official reference has a removable adjustable strap with a 50–62 cm drop. It also has two Toron handles. Drop is the useful starting point for where the bag hangs; the page's drop range should not be relabelled as total strap length.
Louis Vuitton's packing example includes a 6.7-inch smartphone, earphones, lipstick, tissues, keys and sunglasses. The screen-size label is not the phone's exterior length, nor an internal bag measurement. A bulky case or rigid sunglasses case can change fit. This is the brand's example, not a packing test performed by KUANGTU.

Matching numbers are a comparison point, not proof
KU-B46A4448 has the same recorded numbers, 23.5 × 17.5 × 11.5 cm, and its photograph shows two handles and a separate strap. Matching dimensions alone do not prove matching construction, strap drop, hardware or brand identity. Boxes visible in the photograph do not authenticate the item either.
Include the SKU in an enquiry and ask for the opening width, usable internal height and depth, strap adjustment and included accessories. If phone fit matters, provide the dimensions of the phone in its case. The existing unverified identity notice and supplier record remain in place.
Catalogue references to compare
These photographs and records are separate from the official brand sources. Supplier-listed specifications do not authenticate an item or confirm an exact match to a retail model.
