A square optical design within BOLD

The official ALTO 01 page identifies a black acetate frame, clear lenses, a square shape and the signature BOLD symbol on the temples. The square lens opening and surrounding dark rim create a defined outline, while the temple symbol adds a separate side detail.

The supplier photograph associated with ALTO shows a broad black square rim with rounded corners and lenses that appear clear. That appearance is consistent with an optical-style visual reference, but a photograph cannot establish prescription power, lens composition or the configuration available for an order.

A portrait can help show the outline in context, but camera angle and distance affect apparent proportions. Use a straight front photograph and measurements when comparing the actual frame with another model.

Resolve the lens category before discussing a quote

There are three pieces of information to keep separate here: the official clear-lens ALTO 01 listing, the supplier catalogue’s Tinted lens text, and the apparently clear lenses in its photograph. The official listing cannot correct or certify the supplier record on its own, and the photograph cannot resolve the text discrepancy.

Ask whether the offered item has clear lenses, tinted lenses or another specified configuration, and request the matching current photograph and full model code. If the response differs from the image selected, have that difference written into the quotation before approving a sample.

Gentle Monster’s own page offers a prescription option. That describes the official store’s service; it is not evidence that KUANGTU provides prescription fitting or that a particular replacement lens will be suitable. Any prescription work requires a separately confirmed service and an appropriate optical professional.

The lens number does not describe the full square front

For the official ALTO 01 version, Gentle Monster lists 52.7 mm lens width, 22 mm bridge and 146.8 mm temples, with a 150.4 mm frame-front width and 41.1 mm lens height. The latter two values help describe the broad front and deeper square opening.

Two lens widths plus the bridge total 127.4 mm, which is 23 mm less than the official complete front width. The gap demonstrates how much a three-number size reference can leave out. It must not be used as a measurement of the supplier item.

The supplier record lists 52 / 22 / 147 mm and omits front width and lens height. Its bridge number agrees with the official page, but the other values differ. Keep both records intact and ask for confirmation of the actual pair rather than silently substituting official decimals into the supplier specification.

An ALTO enquiry should identify the configuration first

Use SKU archive-1297-alto with the chosen reference image, quantity and destination. Request a clear statement of lens type, the complete model and color code, front width, lens height and inside-temple photographs. Once the configuration is clear, confirm material, packaging and any required supporting documents for the goods being quoted.

The existing enquiry selection and WhatsApp draft on the product page can carry that SKU into the conversation. Keep the lens-category question in the request: an attractive square frame photograph is a starting point, while the confirmed configuration determines what the buyer is actually ordering.
