What are the external features of a speedcube good for?

UV Coating: A popular choice is the UV coating.
Although they may be a bit smoother, these cubes have a premium feel.
A UV finish is a specific type of glossy coating achieved by applying a special lacquer that is then cured under ultraviolet (UV) light.
In addition to a glossy look, the UV finish provides additional protection against scratches and wear, making the cube very durable.

Frosted: A frosted appearance is a slightly rough, grainy finish with a subtle and soft form of gloss.
This texture makes fingerprints and smudges less visible, offers better grip and increased durability against scratches and scuffs.

Matte: A speed cube with a matte appearance has a flat, non-glossy surface that is consistent and even in texture and appearance, with no variations or irregularities a finish that is completely non-reflective.
This texture reduces the visibility of fingerprints and smudges, provides extra grip and creates a quieter visual appearance without reflections.

Black: Traditional speedcubes often have a black base plastic, which provides a strong visual contrast to the colored stickers.
Stickers offer many opportunities for customization, but can wear off or come off over time.
Alternatively, many cubers choose stickerless cubes, which use colored plastic pieces and have no risk of sticker wear.
These remain bright and easy to maintain, although some leagues once had restrictions on their use.

Primary: For a more subtle look, cubes with primary plastic – light gray or off-white base plastic – offer a more muted look.
Although the visual contrast with the colored surfaces is less sharp than with black cubes, they do have a unique and attractive aesthetic.

Gummy: There is also the gecko texture, also known as a gummy finish.
This rubbery coating provides extra grip, which is especially useful for cubers with sweaty hands.
It allows for better control while turning, although it may feel a bit sticky to some users. Glossy: Another popular choice is the glossy finish, which provides a shiny and reflective surface.
Although visually appealing, a glossy finish can offer slightly less grip compared to matte or rubberized finishes. Jelly: Jelly speed cubes are distinguished by their unique and striking aesthetic.
These cubes have a translucent, pastel-colored finish that gives them a fresh, colorful look.
The brightly colored, semi-transparent pieces make the cube look visually appealing and playful.
Despite their unusual appearance, jelly cubes offer the same texture as standard plastic cubes, without the added grip of a gummy finish.
For speedcubers looking not only for performance, but also for a cube that looks unique, jelly cubes are a perfect choice. Metallic: For those looking for something truly unique, there is also a metallic coating.
These give an eye-catching shine and a distinctive look, they are mainly for decorative purposes and are not standard in the speed cube world.
