✨ 2. Key Benefits

• Perfect frost and odor barrier in the freezer: Made for freezing, the plastic is much thicker than regular zipper bags. It prevents food from drying out and the unpleasant "freezer burn" smell from permeating during long-term frozen storage.

• Smart double zipper system: Designed with a tightly closing double zipper structure that completely seals out air and moisture, making it safe for storing liquid foods without fear of leakage.

• Convenient Easy Open Tab: The handle tab on the top of the zipper is designed asymmetrically, allowing it to be opened smoothly and easily without much effort, even with slippery hands or while wearing rubber gloves.

• Overwhelmingly large capacity: With a generous quantity of 360 bags in total, this is Costco's best value-for-money product, allowing you to use them generously for a long time at home or in commercial settings without worrying about the cost.

⭐ 3. Recommended Use Cases

• Case 1: When portioning and freezing meat and fish

When you want to hygienically store large quantities of beef, pork, chicken, or fish in the freezer for a long time, divided into single-meal portions.

• Case 2: When storing large-volume ingredients and frozen foods

When you want to seal leftover frozen foods like dumplings, pizza cheese, or french fries after opening the bag, to maintain their initial freshness.

• Case 3: When preparing meal kits and ingredients in advance

When you want to pre-cut vegetables for soup or ingredients for fried rice and freeze them as meal kits for easy cooking.

• Case 4: When organizing non-kitchen household items

When traveling, use it as a multi-purpose pouch to neatly and safely separate and store wet toiletries, cosmetics, children's toys, or wet clothes.

"The top of the zipper is slightly offset, so it's very convenient to open and close smoothly without having to use a fingernail."

⚠️ Cautions and Notes

• Microwave use caution: This product is for freezer/refrigerator storage. When using in a microwave, it should only be used for defrosting (with the zipper slightly open and for a short time at a low temperature). It is strictly prohibited to heat oily foods at high temperatures, as the plastic may melt.

• No oven or BBQ: Do not place near direct heat sources such as ovens, toasters, or open flames, as the product may deform.

• Caution for infant choking: Keep out of reach of babies and children to prevent them from putting it on their heads or in their mouths.

• Caution for liquid storage: When freezing soups or liquids, the liquid expands as it freezes, so it is recommended to fill the zipper bag only about 80% full, not completely.
