"How many drinks did I have last night?" you ask yourself, realizing that the jackhammering is actually coming from inside your head and not a construction site. When it hurts too much to think, pop on this unique cap that provides cooling relief for hangovers, headaches, eye strain, and migraines. To use, put the nylon cap in the resealable plastic bag and leave in the fridge or freezer for 1–2 hours. Slide it over your head for up to 30 minutes of cooling relief. "I am unwell" is printed across the front. Made in China.
