A shopping list is almost a must-have tool for grocery shopping. People use "Post-it" or note pad as a shopping list. But sometimes it become inconvenient to find it in your bag or pocket when you are carrying heaps of the goods you pick out. Some people even write the list on their hand, despite the ink might stay there for three days.
The main idea is to make shopping process not only more convenient but also elegant. Therefore, I made a shopping list which quite likes "post-it." Users can bind it on their braces. It's easier to skim the list while shopping.
