They were a perfect size for my jaw (be sure to wrap in a tea towel or similar to prevent freeze burn). Always going to keep in the freezer for any knocks or bruises. Great value too. Lasts a good 30 mins held against injury site. Seems good quality. Very easy to use. Review: cheap and effective - i bought these because i had a nasty stye on my eye lid and the doctor advised me to put a hot compress on it 3 times a day. his suggestions was a paper towel in the microwave. obviously this was a bit useless so i came onto desertcart and ordered these with next day delivery. i put one in the microwave for 20 seconds and then put a tea towel over it to rub the liquid around and ‘even out’ the hot spots. i then put it on my eye and it was very soothing. it holds the heat for around 10-15 mins. i put one pack in the microwave about 6 times (uses) but the plastic started to wrinkle and the texture changed. i then binned it and started using another. i put one in the freezer too and used it on a bruise. they are a nice size. good for the price. i would recommend :) ## Features - These Koolpak reusable gel are excellent for the treatment of soft tissue injuries. - Use warm for effective relief from muscular and joint aches. - Lasts longer than a standard Ice or Heat Pack - Ideal for continuous treatment at home - Pack can remain cold for up to 2 hours at room temperature ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B016AAKEHW | | ASIN | B016AAKEHW | | Age Range Description | Adult | | Benefits | Softening,Relaxation,Soothing,Cold,Headache,Relief From,Headaches | | Best Sellers Rank | 4,930 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 29 in Hot & Cold Packs | | Brand Name | Koolpak | | Colour | Blue | | Container Type | Pack | | Country Of Origin | United Kingdom | | Country of origin | United Kingdom | | Customer Reviews | 4.4 4.4 out of 5 stars (1,072) | | Customer reviews | 4.4 4.4 out of 5 stars (1,072) | | Item Form | Gel | | Item model number | KPREUN1 | | Manufacturer | Koolpak | | Manufacturer | Koolpak | | Material Type | Vinyl | | Material Type Free | PVC Free | | Model Name | Koolpak Reusable Hot and Cold Pack | | Number of Items | 20 | | Package Dimensions | 35.29 x 19.6 x 9.8 cm; 2.5 kg | | Product Style | 20 Pack | | Size | 13 x 14cm | | Special Features | Flexible, Reusable | | Unit Count | 20 Count | ## Product Details - **Age range (description):** Adult - **Brand:** Koolpak - **Colour:** Blue - **Material:** Vinyl - **Model name:** Koolpak Reusable Hot and Cold Pack - **Number of items:** 20 - **Package information:** Pack - **Product benefits:** Softening,Relaxation,Soothing,Cold,Headache,Relief From,Headaches - **Special feature:** Flexible, Reusable - **Unit count:** 20 Count ## Images ![Koolpak 20 x Reusable Hot & Cold Gel Pack 13 x 14cm – Microwave Heat Pad & Freezer Ice Pack – Small Compress for Sprains, Swelling, Period Pain & Sports Injuries – Clear Gel - Image 1](https://m.media-amazon.com/images/I/81b69plb8bL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Can we get covers for these?** A: Yes **Q: Do they freeze solid ?** A: Yes they get solid, but still easy to bend to shape, really useful **Q: Can these be used to keep insulin cool?** A: not sure about medication but they stayed frozen in my coolbox (about 25 of them) for 24 hours and kept the beers cold if that helps, much easier than the hard plastic gel blocks, less messy than ice.
