The selected UK variant
The maker’s public product-data response identifies variant 54851699343737 as 8 ml, price 425p and SKU 884955085158. The family page defaults to a Half Pan at£3.25. That default is not the selected 8 ml ticket. The selected reference is£4.25 for one 8 ml tube, not a half pan or 21 ml package.
Keep identifiers separate
The colour number is 660 and the maker identifies pigmentPB29. The product-data SKU is not the same field as the colour number. Some family images carry older or different barcode strings. The journal preserves the actual selected variant record rather than taking a barcode from an unselected image.
A replenishment example
Two exact 8 ml tubes provide sixteen declared millilitres across two tubes and cost£8.50 merchandise at the observed ticket. They do not become one uninterrupted 16 ml tube or an established number of pans. The site has not measured fill volume or pigment concentration and cannot turn that total into a painting-yield forecast.
A concrete order check
The public maker response also lists a21ml variant at860p and a Half Pan at325p. Those are separate offers. A page headed Ultramarine is therefore insufficient to identify the purchased quantity. Keep the8ml variant identifier with425p when recording this specific observation;do not select the lowest family price and retain the larger tube volume.
Version limits
The exact variant URL was inaccessible to the web reader, while the public maker product-data endpoint returned the selected size, price and SKU. That distinction is recorded. Actual supplied labels, current stock and the applicable UK SDS remain pending; family-page safety wording is not a full received-label audit.
