The smaller ones might be a bit big for a kid's lunchbox but for keeping a bigger bag of food cold, they're amazing! ### ⭐⭐⭐⭐ Effective ❄️❄️❄️ *by G***Y on 4 June 2021* These are slim freezer blocks that fit comfortably into most cool bags and boxes. As such, they can be inserted between bottles and tupperware boxes to give maximum and even cooling. I use them in our Thermos 30l cool bag where they fit perfectly. They take about 3 hours to freeze solid in a domestic freezer. They do swell a bit in the process - but that's normal for blocks of this type. They are relatively lightweight but seem to be very effective. In a well stocked cool bag, they easily last for 6+ hours - even in a high ambient temperature (but don't leave the cool bag directly in the sun!). Thus far, we have no complaints ☺️☺️ ## Frequently Bought Together - Thermos Freeze Boards, 1 x 800 g/2 x 400 g, Pack of 3, Blue - Thermos 158035 Family Cool Bag, Navy, 30 Litre - KEPLIN Freezer Blocks for Cooler Bags - Reusable Ice Packs for Lunch box, Travel, Picnic, and Outdoor Activities Multicolour (6 Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/49247090-3er-pack-freeze-boards-1-x-800-g-2-x](https://www.desertcart.co.th/products/49247090-3er-pack-freeze-boards-1-x-800-g-2-x) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
