Pretty sure this is a common cacti but I'm a newbie lol

I found this cacti at a garden centre; unfortunately they had stuck a cocktail stick into it and a deep wound was inflicted. It has partially healed. I am very curious to find out what cacti it is? I'm a total newbie but I'm fairly fascinated by cacti! Thanks!

Some Parodia / Notocactus. Don't know the specific species, though.

[Nevan1111]

It is 6cm tall and it is taller than it is wide.

Notocactus magnificent
Balloon cacti maybe?

[Nevan1111]

parodia magnifica? Looks about right! Thanks!

[Nevan1111]

Or maybe Parodia warasii

If the skin is as green as it looks in the picture, likely warasii. Parodia magnifica is more blue.

I'd say balloon cacti are more powdery greenish then bluish- or atleast that's how i see it

[greenknight]

All "blue" cacti have a powdery bloom on the surface which produces a blue appearance, there's no blue pigment. It needs good light to develop, though - it could be either one depending on the growing conditions.

Yes they only get there bluish color on their skin when the light forms the powdery coating on the cactus skin
