Insulated Pint Glasses

My mother recently put her mother in a nursing home. After cleaning out my grandmother's house, mom brought home a dozen or so drinking glasses. They are jelly jar glasses that so many of my family had in their cupboards. I recently purchased a couple of Guinness tulip shaped pint glasses. So what is the first glass anyone grabs when they pours themselves a glass of iced tea? No, not the dime a dozen jelly glasses. The pint glass. Every time. So, as much as I want these insulated pint glasses from Red Envelope, I'm not buying them.
