Thermo bottle Correct exams

This thermos keeps your water cool for 24 hours and your tea hot for about 12 hours.   It would give you time to correct a few exams while you drink it, but that depends on you, of course.   Reusable and sustainable thermal bottle in black and matte finish with a capacity of 500ml.   Made of 18/8 stainless steel with the phrase “No, I have not corrected your exams yet” printed in white.   This double-wall insulated bottle keeps your drinks cold for 24 hours and your drinks hot for 12 hours. ¡Doesn't drip!   Always carry it with you without worrying about spilling anything in your bag.   BPA free.     Not dishwasher safe.   It is delivered in a cardboard box with a fun design, ideal if it is a gift.
