It depends on the product format. Basic skincare typically starts from 5,000–10,000 units. General patch products start from 30,000 pieces, and custom printed eye patches from 30,000–50,000 pairs. Hydrogel eye patches are usually packed 30 pairs per jar, with an MOQ of 5,000 jars. Hydrogel face masks start from 35,000–80,000 sheets, and sheet masks from 50,000–100,000 sheets. One thing worth knowing: patches and masks are produced as individual pieces or pairs and then packed into retail sets, so the production quantity and the number of finished retail products aren't the same — 5,000 jars at 30 pairs each is 5,000 finished retail products. These are the practical minimum production quantities required by Korean manufacturers, not a B4 LAB policy. Final quantities are confirmed by scope.
