I bought these glasses for my 90 yr old parents bec the glasses are small and light, the handle is easy to grab and they're glass not plastic. My parents really like them. They'll use these glasses at home and in the car. I suggested they take them in restaurants so they can drink filtered water from home not tap water at the restaurant. The metal lids screw on and off very easily and have a tight seal. The handmade glass straws are great. I removed the plastic grommet in the hole in the lid so these glass straws fit perfectly. Photos attached of glasses, glass straws and removable grommets.
