自製螢光筆 - 瘋狂夏日

Mixing my own highlighter inks from the little bottles was way more fun than expected, and the decorative bits let me make each pen look totally different. Took maybe half an hour to assemble, and now I actually enjoy using them for my study notes.

My niece spent a whole rainy afternoon mixing the ink colors and sticking on the little character decorations, and she barely looked up from the table. The two highlighters write smoothly once assembled, and the customization part kept her way busier than I expected.

The two highlighters actually work well once assembled, and my son loved choosing the ink colors. Decorating them took him almost an hour, which kept him busy on a Sunday afternoon.
