Frequently Asked Questions
-
The 30g square glass jar with gold lid is the eye-cream and treatment size — eye creams, lip masks, concentrated retinol or vitamin C creams, spot and brightening treatments, and travel or discovery sizes of a face cream. Brands use it for the products that are dosed a pea at a time and priced by potency, not volume. The square body gives flat faces that take a label cleanly.
-
About four to six weeks of daily use for an eye cream or treatment. Eye and treatment creams are used a pea at a time, so a 30g jar lasts as long as a 50g face cream does — that is the logic of the size. Print the number of days on the label; it is the question customers ask before a repeat order.
-
Yes — the jar ships with its gold lid and an inner wad under it. The lid is precision-threaded and the wad seals the mouth, so a cream or balm stays sealed from air and fingers through daily use and the product cannot creep into the threads. It is a jar for creams, balms, butters and scrubs; for a liquid, choose a bottle.
-
Yes — this jar belongs to the Square Glass Bottles & Jars with Luxurious Gold Lids family (C51), and the same lid runs across the serum, lotion and toner bottles in it. Pick this jar for the cream, then the C51 bottles for the rest of the routine, and the whole line shares one lid on the shelf. See the C51 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.
-
The flat faces take a rectangular label on the front and a second on the back, with the ingredients on the base — the layout that photographs best on a square jar. 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, lid and wad 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.
