Cup lid and “Tempered Steel” biography for Father’s Day gift

Give your favorite Dad a book about his special interests. Add a Kup Kap (cup lid) to put on his mug of hot tea or coffee while he's reading in his comfy chair. His brew will stay hotter, longer for at least thirty minutes because the Kup Kap is insulated with Thinsulate Insulation by 3M used in winter clothing!
