I just bought this on Amazon the other day. The sparkly blue and red colors in the fifth photo were inserted into the pen once. The red one was slightly bent when it arrived, so it's a bit shorter. I'm selling this because the filament I bought this time isn't compatible with the 3D pen I have. 【Product Description】 This is a 40-color set of PLA filament for 3D pens. It can be used with 3D pens that support a diameter of 1.75mm, such as 3Doodler FLOW / PRO, MYNT3D, and SCRIB3D. With a wide variety of 40 colors, including popular colors, transparent colors, fluorescent colors, glitter colors, and glow-in-the-dark colors, it's recommended for creating artwork and for children's crafts. ・Material: PLA (Polylactic Acid) ・Diameter: 1.75mm ・Contents: 40 colors (approx. 3m each / approx. 120m total) ・Safe, non-toxic, and easy-to-handle material with little odor. *Please note that it is not compatible with 3Doodler Create+ and Start+. 【Condition】 New, unused Two colors were used once, but they are not melted. 【Shipping】 Will be shipped with waterproof packaging.
