ARTISTRO 12支閃光玻璃繪畫筆，岩石彩繪、陶瓷、木材、布料、剪貼簿、DIY手工製作、著色 - 壓克力顏料筆極細頭0.7mm

I’ve been using these on glass jars and ceramic mugs, and the glitter actually stays put once it dries—no smudging even after handling. The extra-fine tip lets me do tiny details without the ink pooling or skipping. Only wish the set had more colors, but the shimmer payoff is worth it.

These handled rocks I painted for my sister’s garden beautifully, the shimmer is subtle but really pops in sunlight. Ink dried fast enough that I could layer colors without smudging, though you do need a light hand to keep the coverage even.

The extra-fine 0.7mm tip is perfect for adding tiny sparkly details to my rock painting projects without any bleeding. Ink dries fast and the glitter actually stays put, so I've been using them on glass jars too and they still shine after a week.
