The KOKUYO Checkle set combines two types of memory pens to help you study more efficiently. Just overlay the included red sheet to instantly hide the highlighted or handwritten content.

Key Features

• Green Highlighting Pen: Designed to be used over printed text (like textbooks or study guides), this pen allows you to conceal words under the red sheet without messy ink bleed-through. Once you've mastered a section, simply erase the green ink using the included erasing pen.
• Orange Writing Pen: Perfect for writing key notes or answers in notebooks. Anything written in orange becomes hidden under the red sheet—ideal for quick review before tests.

This all-in-one set includes both pens, a red masking sheet, and an erasing pen—everything you need to streamline your memorization process.
