desertcart.com: Ice Packs for Lunch Box, 4 Pack, 6 x 4 x 0.7 in | Slim freezer packs, soak-to-activate, reusable & food-safe, space-saving, cold pack for bento, work, picnic, camping, cooler : Sports & Outdoors

Review: Cool design. Works well. Stays cold long time - I got these for my diaper bag to keep my milk cold on the go!! It’s super cool how you wet them and they soak it all in and then freeze.
Review: Never leaky or soggy - These little ice packs were very deceiving at first. The instructions were soak in water and then freeze. My brain automatically thought they would loose the liquid every time the defrosted. They don’t. They are always dry never soggy. They are perfect for lunch boxes or a family cooler on a day at the beach. We have been using them now for months and they haven’t leaked once. The price was nice too

## Features

- EASY 3-STEP ACTIVATION： Simply soak the ice pack in water for 3–5 minutes, wipe it dry, then freeze for 3 hours or overnight. The gel activates quickly—no dry ice, no messy cubes. Reusable hundreds of times.
- SLIM DESIGN FOR LUNCH BAGS & BENTO BOXES： Each pack measures just 6"×4"×0.7". Its ultra-slim profile slides neatly into lunch bags, bento boxes, school lunch kits, office meal prep containers, and small coolers. Lies flat against food or drink containers to save valuable space.
- LONG-LASTING COLD, LEAK-RESISTANT： Thick cooling gel and a puncture-resistant outer layer keep contents cold for hours. The leak-resistant seal prevents messy leaks and soggy food—so your lunch stays fresh and dry.
- MADE FOR DAILY LUNCH USE： Purpose-built to keep meals, snacks, and drinks chilled from morning through lunch. Ideal for school lunch, office lunches, bento boxes, and meal prep—fits right into your daily routine.
- BPA-FREE & NON-TOXIC： Crafted from non-toxic, 100% BPA-free materials that are safe for direct contact with food. Great for breast milk bags, baby food, fruit, and groceries. A reusable, eco-friendly alternative to disposable ice packs.

## Questions & Answers

**Q: Why are there only four sheets inside after opening the package?**
A: Hi, the sheet must absorb water before it can be used properly.

**Q: Does it need to be soaked in water before each use?**
A: No need to soak it every time. Our product features dry white resin pellets inside and waterproof fabric outside. Once water is absorbed, it locks it in to prevent leakage.

**Q: Can ice packs be frozen or heated?**
A: It is suitable for both cold and hot use. It can be placed in the freezer for freezing, and can also be heated in a microwave or hot water.
