Frequently Asked Questions
-
The 20g glass jar with unique-shaped black lid is the small-format jar — lip and eye balms, cuticle and spot treatments, solid perfumes, samples and travel sizes of a face cream. It is the size a brand uses for a trial pot, a PR kit or a discovery set, and for high-value balms where a little goes a long way.
-
About two to three weeks as a trial size, or months as a balm. A 20g jar of face cream used morning and night is a fortnight's supply — which is exactly why brands use it for samples and travel — while a lip or cuticle balm dabbed once a day lasts far longer. Print the number of days on the label; it is the question customers ask before they buy the full size.
-
Yes — the jar ships with its unique-shaped black lid fitted. The lid is precision-threaded, so a cream or balm stays sealed from air and fingers through daily use. It is a jar for creams, balms, butters and scrubs; for a liquid, choose a bottle. If your filling line needs an inner disc under the lid, ask on WhatsApp before you order in bulk.
-
Yes — this jar belongs to the Glass Bottles & Jars with Unique Black Lids family (C14), and the same lid runs across the serum, lotion and toner bottles in it. Pick this jar for the cream, then the C14 bottles for the rest of the routine, and the whole line shares one lid on the shelf. See the C14 family collection.
-
No — this is clear glass, so it lets light through; it shows the texture and colour of the cream and photographs best. That is the right choice for stable creams, water-based gels and products sold in a carton. For vitamin C, retinol or essential-oil formulas that fade under UV, choose an amber jar from the Glass Jars for Creams & Lotions collection, or keep this jar in its box.
-
A wrap-around label on the body, or a round label on the lid top with the ingredients on the base — both work on a round jar, and the lid-top version leaves the glass and the cream visible. From 1,000 pieces the glass can be screen-printed, hot-foil stamped, frosted or painted to order; send the artwork on WhatsApp and we will say what fits this size.
-
They ship straight from the factory cartons, not pre-washed or sterilised — wash the jar and lid with warm water and a mild detergent, rinse, sterilise (a 70% isopropyl-alcohol rinse, or hot water for the glass) and air-dry fully, mouth down. Fill only a dry jar, and declare the net weight from a test fill of your own formula: the size on the jar is its capacity, and what it weighs filled depends on the density of the cream.
-
