Waso FAQ
Where is the mark on the YUZU-C Sleeping Mask?
Check the jar base, lower wall and carton flaps first.
Is the item number a production code?
No. It identifies the retail product and is different from a manufacturing mark.
WASO marks on botanical skincare bottles, jars and refills
Before you rely on the decoded date
- Inspect the jar or bottle base, tube crimp, refill seal and the end or bottom flap of the carton. On a translucent jar, check both the base label and the clear wall near its lower edge.
- YUZU-C and KOSHIRICE identify product families. A long item number such as the one printed on WASO product range, the 50 mL size, barcode and recycling marks are not production dates; look for a separate compact ink or embossed mark.
Common lookup mistakes
- Keep the refill pouch and outer carton until their marks have been photographed.
- Include WASO and the exact family name when saving the image, because Shiseido sells several distinct collections.
