Review on 🧊 6-Pack Slim and Lightweight Dynamic Gear Ice Packs for Lunch Boxes, Coolers, and Camping - Reusable Freezer Cold Packs by Brandon Wynen

They fit perfectly in my Coleman lunch box (https://www.amazon.com/gp/product/B006HFC3K2/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1). They fit exactly both vertically and horizontally. They're easy to stack and the more you stack them, the longer they stay cold. I pack my lunch at 7:30 and get home at 6:30 and at the end of the day they are still frozen. I love how versatile they are and how cold they keep my lunch. Highly recommended.
