# Colourbing Glow-in-the-Dark PETG Filament, 1.75 mm, 4 Colors

Colors: Colourbing glow-in-the-dark PETG filament is offered as four 250 g spools in green, blue, yellow, and purple. Its luminous effect and stated PETG toughness suit decorative prints and functional small parts, but the listing's separate material field says Polylactic Acid, so confirm the material before choosing it for a PETG-specific project.

## At a glance

- The listing describes four luminous colors and suggests charging finished prints with sunlight or UV light before use.
- Pre-drying, vacuum sealing with desiccant, and neatly wound spools are manufacturer claims intended to limit moisture-related printing problems and tangles.
- The seller describes the material as tougher and less brittle than standard PLA, with strong layer bonding and relatively low shrinkage.

## Pros

- Four smaller spools provide green, blue, yellow, and purple for trying multiple luminous colors without buying separate full-size spools.
- The listing describes pre-drying and sealed packaging with desiccant, useful for managing moisture-sensitive filament during storage.
- A printable spool adapter is suggested for systems needing larger spool dimensions, though fit depends on the printer and spool setup.

## Cons

- The 250 g spools contain less filament per spool than a typical full-size spool, so larger projects may need more frequent changes.

## Before you buy

- The listing is contradictory about material: its title and feature copy identify PETG, while the technical material field says Polylactic Acid. The package quantity is also inconsistent in product details, which say 4 items and 8 packs, while the title and feature copy describe four 250 g spools totaling 1 kg. Confirm the selected listing's material and bundle configuration before buying. Glow brightness and duration vary with color, light exposure, and printed wall thickness.

## A good fit for

- Makers who want several luminous colors in smaller quantities for ornaments, tags, keychains, organizers, and other decorative prints.
- Users looking for glow filament for functional small parts, provided they verify that the selected listing is PETG and their printer is configured for that material.

## Less suited to

- Buyers who need a clearly confirmed PETG formulation without checking the conflicting material field.
- Projects requiring a large uninterrupted amount of one color, since each spool is listed as 250 g.

## Customer feedback

Aggregate customer ratings lean positive overall, but include ratings across the full star range. With no review-summary evidence, they do not establish specific strengths, complaints, or performance reasons. Treat them as limited context rather than proof of print quality or glow performance.

## Frequently asked questions

### Is this definitely PETG filament?
The title and feature text call it PETG, but the technical material field says Polylactic Acid. Confirm the material with the selected listing before purchasing for a material-specific print.
### What colors and spool sizes are described?
The title and feature copy describe green, blue, yellow, and purple, with four spools of 250 g each. The product details also list 4 items and 8 packs, so confirm the bundle configuration.
### How is the glow effect charged?
The listing recommends exposing finished prints to sunlight or UV light. It says brightness and duration vary with color, exposure, and printed wall thickness.
### Will these spools fit my printer?
The filament is listed as 1.75 millimeters. The listing says some systems may require a printable spool adapter and notes that adapter fit varies with spool size and printer configuration.
