Three distinct order lines
The selections are Cotman Ultramarine 8 ml tube, UK variant 54851699343737/SKU 884955085158; Cotman Sketchers’ Pocket Set, SKU 5012572005784, with twelve assorted half pans and a brush; and Arches hot-pressed 23×31 cm gummed pad, PPAP23HP, with twelve sheets. Their purchase units are not equivalent quantities of watercolour material.
Match the existing brief
A request for a single Ultramarine tube cannot be filled by a twelve-colour set merely because Ultramarine is among its listed colours. A request for a twelve-sheet pad cannot be fulfilled by twelve half pans. Keep the product name, format and quantity on separate fields rather than comparing the three tickets as substitutes.
A concrete order note
Write “Cotman Ultramarine, colour 660, 8 ml, SKU 884955085158” instead of “blue watercolour”. For paper, write “Arches Aquarelle, hot pressed, 300 gsm, 23×31 cm, twelve-sheet gummed pad, PPAP23HP”. Those descriptions answer different purchasing questions and prevent a changed size or surface from disappearing behind a familiar brand name.
A concrete order check
For a studio inventory sheet,use three columns for the required specification,the selected retail offer and its actual denominator. The tube row might count declared millilitres,the set row complete assorted sets,and the paper row matching physical sheets. A grand item count across those three columns would not represent a useful common stock unit.
