These are AMAZING for migraines and even Cluster Headaches which are a million times worse (I have them). They have some sort of magic cooling menthol gel that lasts for 8 hours and it definitely soothes the pain from migraines. I'd pay more that the RRP for these as they help so much so for them to be half price (£1.64) is fabulous for me and I have stocked up on them.
Deal runs out on 5th jan. They also have kool n soothe fever for £1.30 for kids or adults with flu or colds etc
