A teacher's gift any teacher can useI purchased this insulated water bottle for my niece's teacher. The insulation gives the option of hot or cold drinks, and the twist off cap prevents devastating spills on desks. As a retired teacher myself, this caught my attention. . . a useful personalized gift that also expresses gratitude. I highly recommend this purchase for any teacher, especially those teachers who tend to leave their drink in the office, the library, or the art room!!!
