Medicube Collagen Overnight Wrapping Peel-Off Facial Mask

•  Magical Reusable Ink: Equipped with a specialized plant-based magic pen. The ink fades within 15–20 minutes and disappears completely in under an hour, allowing children to practice infinitely without wasting paper.
•  3D Groove Design: Features distinct indented, three-dimensional tracks that gently guide a child's pen strokes. This physically trains muscle memory for proper letter, number, and shape formation.
•  Comprehensive 4-Book Set: Typically covers four foundational early-childhood learning themes: Alphabet, Numbers, Math, and Drawing.
•  Ergonomic Posture Correction: Includes a soft silicone pen grip aid designed to teach toddlers the correct tripod grip, preventing hand fatigue and establishing good writing habits early.

•  Core Materials: The books are constructed from thick, high-quality cardboard/laminated coated paper designed to resist ink bleed-through, staining, or tearing from eager toddlers. The pen holder grip is made from 100% non-toxic, soft silicone.

•  Care Instructions:

•  Keep the copybooks completely dry; avoid liquid exposure as water can damage the grooved paper layers.
•  Only use the provided proprietary magic ink refills; standard ballpoint or gel pens will permanently stain the pages and will not fade.
•  Wipe clean with a completely dry microfiber cloth if dust accumulates.

1. Assemble the Pen: Twist open the magic pen shell, insert one of the disappearing ink refills, and securely close it back up.

2. Slide on the Grip: Slide the soft silicone ergonomic fish/grip tool onto the lower barrel of the pen. Position it where the child's fingers naturally rest to establish proper tripod writing posture.

3. Trace the Grooves: Have the child select a book and guide their pen along the physical 3D indented tracks. The physical grooves keep the hand from drifting.

4. Watch it Fade: Once complete, leave the book open. The special ink will gradually fade in 15–20 minutes and vanish completely within an hour, leaving the pages pristine and ready for the next practice session.
