Homestec A4 Reusable Erasable Notebook Pen & Cloth Microwave Heating Waterproof

An eco-friendly alternative to traditional paper notebooks, featuring special pages that can be written on with an erasable pen, scanned to a cloud service via an app, and then wiped clean for reuse hundreds of times.
The notebook contains pages made from a synthetic, tear-proof, and waterproof material that feels smoother than regular paper. Each page can be erased and reused over 500 times, significantly reducing paper waste and saving money.
The notebook is designed for use with specific erasable pens, Frixion style gel pens (two pens are often included in the set). The ink dries quickly (within about 15 seconds, according to some sources) to prevent smudging.
Multiple Erasing Methods:
The eraser on the end of the included pen can correct small mistakes.
A slightly damp microfiber cloth (often included) can be used to wipe entire pages clean, leaving no residue.
The ink is thermo-sensitive and disappears when exposed to heat, such as from a hair dryer or microwave heating (check manufacturer instructions for safe use).  
The smart aspect comes from its compatibility with scanning apps, such as the official "NEWYES NOTE" app or third -party apps like CamScanner and Microsoft Office Lens.
Users can scan their handwritten notes to convert them into digital formats  (like PDF or JPG) and send them to cloud storage services like Google Drive, Dropbox, Evernote, OneNote, and iCloud.
The notebook is a large A4 size (approx. 28.5 x 22.4cm or 11.2 x 8.8 inches) and two different types of pages (lined pages and dot-grid pages).
