At the 5th China Electronic Information Fair (CITE 2017), a light blackboard called HowShow appeared. It felt that the small blackboard was inspired by the magnetic Sketchpad we played with when we were young. It was also written to remove pictures instantly. Now, with advanced technology, this thing has a higher resolution. More convenient and more tall.

The 57-inch light blackboard was the first one to catch the eye, and everyone loved it so much that it attracted exhibitors of all ages to experience it.

There are 8.5-inch or 12-inch light blackboards on the stand next to each other. The exhibitors are also waiting in line for personal experience. We can see that people may have more or less feelings for the magnetic sketchpad. Some friends buy the product directly after experiencing it and are ready to go home for their children. The fact proves that the product is true. It's very hot. The products sold on the spot are sold out soon.

This product is developed by Shenzhen HaoWrite Technology Co., Ltd. No matter what is written, it can be removed by pressing the clearance button in the center above. Although the pen is not used, the product is equipped with a pen. This product eliminates three hidden dangers of unsafe, unsafe and unhealthy conditions, such as the fundamental prevention of dust inhalation from traditional blackboards.

The panel is made of flexible LCD panel, and the power supply is replaceable button battery. The whole blackboard is only 4.5mm thick. It is very portable. At the same time, the product has magnets attached to the back, so it can be adsorbed to the refrigerator instead of convenience stickers. It can also be used as arithmetic straw paper.

The favorite thing is, don't be afraid to erase what you've written. With App, you can keep the picture.
