Yes transparent water bottle is allowed

See your neet admit card 2nd page

Hello aspirant ,

Unfortunately water bottle is not allowed . However water will be provided in the examination hall. Any item that can be used for unfair means are barred from being taken to the examination hall. You cannot even wear a wrist watch , instead a wall clock will definitely be provided in the examination hall.

hope this helps.

Hello student I'm sorry to inform you but no you're not allowed to carry Bisleri or Kinley water bottle inside the examination center. Due to Covid-19 students are allowed to carry personal transparent water bottles, however diabetics student are allowed to carry fresh fruits/sugar tablets and transparent water bottles inside the examination center.
