## At a glance

- The bundle is described as four 250 g spools, with two named blue options and two rainbow variants.
- The listing says the filament glows after absorbing sunlight or UV light, and that glow strength and duration depend on the charging source and exposure.
- The listing claims ±0.03 mm diameter accuracy and compatibility with most 1.75 mm FDM printers.

## Pros

- Four small spools let makers try several glow colors without buying full-size rolls.
- The glow effect offers a distinct look for decorations, toys, miniatures, signs, and other display prints.
- The listing says each spool is vacuum sealed with a desiccant bag for storage protection.

## Cons

- Customer feedback mentions brittleness and says the filament breaks more easily, a practical concern when handling or feeding it.

## Specifications

### Identity
- Brand: Colourbing
- Colors: Firefly Blue/Sky Blue/Rainbow5/Rainbow6
- Additional features: Glow In The Dark, Rainbow Color, Multi-color
### Dimensions and installation
- Filament diameter: 1.75 millimeters
- Weight listed: 2.2 pounds
### Materials and protection

## Before you buy

- Glow intensity depends on the light source and exposure time, then fades as stored light energy is released. The listing describes four 250 g spools, while the listed total item weight is 2.2 pounds, so the bundle's stated weights are inconsistent. The 2.2-pound figure is a listing detail, not a confirmed spool-net-weight total.

## A good fit for

- Makers who want small amounts of multiple glow-in-the-dark colors for decorative or novelty prints.
- Users with a 1.75 mm FDM printer looking to try luminous PLA+ before committing to larger rolls.

## Less suited to

- Buyers who need a clearly established brittle-resistant filament or dependable continuous feeding without handling concerns.
- Projects requiring a specified glow duration or consistent brightness, since the listing provides no fixed performance figure.

## Customer feedback

Customer feedback highlights decent printability but also reports brittleness and easier breakage. For buyers using the listing's claimed 1.75 mm FDM compatibility, the printability comments are relevant, while the breakage concerns matter during handling and feeding. Ratings lean positive overall but include a notable low-star share, so the aggregate does not establish a consistent experience.
- Positive themes: Customers describe the filament as printing decently.
- Negative themes: Customers report brittleness and easier breakage.

## Frequently asked questions

### What colors are listed in this bundle?
The title names Firefly Blue, Sky Blue, Rainbow5, and Rainbow6, with four 250 g spools described in the feature text.

No fixed duration is stated. The listing says sunlight or UV exposure charges the filament and that the glow naturally fades as stored light energy is released.

Customer feedback describes printability as decent but also reports brittleness and easier breakage. Consider that trade-off when handling and feeding the filament.
