B-MARKER 是專為教師與學生設計的雙頭白板筆。隨著粉筆因衛生與健康問題逐漸被淘汰，傳統白板筆卻缺乏粉筆的大面積塗色與繪圖功能。B-MARKER 採側邊按壓機制，可伸出不同筆頭，包括可同時繪製多條線的斜尖筆與適用於大面積填色的平尖筆。內部墨水匣連通棉管，讓兩端皆可出墨並補充墨水。不僅滿足精細書寫需求，也能快速繪製圖形，提升教學效率，幫助學生直觀理解複雜概念。

B-MARKER

B-MARKER is a dual-tip whiteboard marker designed specifically for teachers and students. Addresses this gap with a side-press mechanism that extends a long-tip nib, featuring a slanted tip for drawing multiple lines simultaneously and a flat tip for efficient large-area coloring. Internally, a connected ink cartridge and cotton tube enable dual-end ink flow and easy refilling. This design supports precise writing and allows for quick shape rendering, enhancing teaching efficiency and helping students visualize complex concepts more effectively.
