In the e-commerce operation of water based lubricant, many sellers are caught between "large economical bottles" and "small portable packs." The essence of product selection is the battle between profit models and consumption scenarios. Although large bottles seem to have a higher unit price and larger volume, in-depth data analysis reveals that portable packs show remarkable advantages in profit margin, attachment rate, and logistics efficiency, becoming the profit core for many emerging brands.

Large bottles (over 200ml) are suitable for frequent home use. Although they help build brand loyalty, their large size and weight result in high cross-border logistics and storage costs. Market prices are transparent, and profit margins are often eroded by price wars. Portable packs (pouches or 30ml small bottles) target business trips, travel, and trial scenarios. Their compact size not only greatly reduces shipping costs but also has strong "fast-moving consumer goods" characteristics. Especially in adult stores or hotel vending machine channels, portable packs often have profit margins more than twice those of large bottles. For new brands, using portable packs to lower the user trial barrier is an effective tool for customer acquisition and traffic generation.

Smart brands typically adopt a "portable pack for traffic attraction, large bottle for repurchase" combined strategy. When outsourcing customization, they can use the same mature formula to develop multiple packaging specifications. Portable packs can use differentiated visual designs to enhance premium value, while large bottles establish a professional image through medical-grade certification. By flexibly combining specifications, brands can effectively cover multi-dimensional consumer needs and, within the complex e-commerce traffic system, use the high turnover rate of portable packs to improve overall inventory turnover.
