Where is a fwee batch code?
Check the pot or compact underside, lip tube base and the outer-carton flap.
Check a fwee makeup lot
fwee is known for pot-format lip-and-cheek colour, including Blurry Pudding Pot and Glowy Jelly Pot, alongside gloss, cushion and other Korean colour makeup. Compact shade labels such as ND, RS, MV, BS or JN followed by digits identify colour families and shades, not the production lot.
fwee FAQ
Is RS03 or BS01 a batch code?
No. It identifies a shade family and colour.
Are Pudding Pot and Jelly Pot the same product?
No. They are different formulas, so retain the exact name when checking.
Separate shade families from the production mark
Before you rely on the decoded date
- For a pot or cushion, inspect the underside label and compact rim; for gloss and lip products, check the tube base, stopper area and carton flap. Korean and export stickers may cover the original label, so photograph both layers without removing required regulatory text.
- Record the complete formula and shade separately. Pudding Pot and Jelly Pot use similar pot packaging but different textures, while a shade code such as RS03 or BS01 is retail colour information and must not be decoded as a manufacturing date.
Common lookup mistakes
- Use clean fingers or tools with pot products and close the lid promptly; contamination and drying can alter the surface before the formula's expected life ends.
- Keep cushion and lip products away from heat. Replace after seal damage, persistent odour, colour or texture change, or irritation regardless of the estimated date.
