Vibrant Colors & Unique Effects: The bundle includes Glitter Galaxy Black, Chameleon Blue, Glow-in-the-Dark Green Starry, and Glitter Gold. Users praise the vibrant colors and the glow effect, though some note it varies with light sources.

Printing Performance: Recommended for 0.6mm nozzles and >0.2mm layer thickness to avoid clogging. Some users faced brittleness and clogging issues, especially with smaller nozzles, but others reported smooth printing after adjusting temperatures (180-220°C).

Quality & Durability: The filament boasts good layer adhesion, minimal warping, and rigidity. However, a few users encountered brittle filaments or color-shifting challenges.

Value for Money: At $21.99 (with occasional discounts), this 4-color pack offers variety and is ideal for sampling different finishes.

Final Verdict: A great choice for those seeking colorful, glittery prints, but requires some tweaking in settings for optimal results.
