These are very fitting replacements for my customized cups that have the plastic straws that vanish after the first/second wash. In majority of the cups I have they do fit nicely into the tops and do not affect the top being screwed on. They have a non-tasting or non-adding taste to the liquids I drink how some plastic straws leave a weird plastic taste no matter how much you wash them. They come with a cleaning rod that is easy to handle, and easy to clean after use. Just put it under hot water and let it rinse off then put it up to dry out. My husband has dropped one of these a couple times now onto wood flooring, and it has yet to crack or break. This amazed me as I assumed they would since being glass. These are very handy to have and to use!
