I think it is useful. Take my product as an example. The product is designed to open the lid upwards, so I mark how to open the lid under the lid, so that consumers do not need to ask how to open the lid.
Some people may ask, why is it designed this way? Because the design of each product comes from the designer’s inspiration, this design method is considered for functionality, safety, space, appearance, preventing the cover from being lost, etc.
Therefore, in order to make it easier for consumers to use, it is very important to have good labeling instructions.
