Which part of the Koji Honpo package carries the lot mark?
For Koji Honpo, work from the tube base and carton on mascara to the compact underside and hinge area on makeup compacts. This keeps container-specific labels separate.
Koji Honpo makeup lot code
Before checking the Koji Honpo date, separate the product format from the printed identifiers around it. Mascara, eye color, and makeup compacts may use different surfaces for manufacturing, retail and use-period information.
Koji Honpo FAQ
Does the long number on Koji Honpo identify its production run?
No. Koji Honpo eye products use shade numbers, Japanese references, barcodes, capacity, and PAO for other purposes. Select the separate variable mark on the tube, compact, pencil, or carton.
Does the Koji Honpo code show how the item was stored?
No. A Koji Honpo code cannot record eye-product contamination, drying after opening, or heat exposure. Applicator hygiene and PAO guidance remain essential.
Reading Koji Honpo eye-makeup codes
Before you rely on the decoded date
- On the Koji Honpo mascara, inspect the tube base and carton; for the eye color format, compare the compact underside, pencil barrel or carton. If the carton carries another short string, retain a photo of both marks.
- Koji Honpo eye products may carry shade numbers, Japanese product references, volume, and a barcode on a small pack. Compare the tube or compact with its carton and choose the distinct variable production mark, not a shade identifier.
Common lookup mistakes
- Koji Honpo mascara tubes, pencils, and compacts have little printing space. Photograph the mark at close range and compare the carton so shade references are not copied as lot characters.
- Treat the Koji Honpo production estimate separately from eye-area hygiene. Replace a mascara or eye product when its applicator, scent, texture, or cleanliness changes, even when the estimated manufacturing period appears recent.
