The Loop Cup encourages you to drink 8 cups of water a day. The primary reason people fail to drink sufficient amount of water is that they arent aware of how much water they are drinking. Loop Cup helps you to check the water intake by simply rotating the holder after drinking a cup of water (250ml) then you can drink 2 liter of water a day. The silicone holder is heat-resistant and has 8 holes inside which interlocks with a bump on the cup so it stops at the proper position to show the number graphic. The main material of cup is PLA which is non-toxic and biodegradable. The Loop cup simply improves the habit to drink water and motivate your healthier life.
