4 Pair / 8 Pcs Replacement Silicone Thumb Grip Stick Analog Joystick Cap Cover for Ps3 / Ps4 / Ps5 / Xbox 360 / Xbox One Game Controllers Black

Joystick on my ps4 controller has worn off all of the rubber, it's just the hard plastic now. Will these fit without the rubber?Or will it be too big?

Could these work on an N64 controller?

Will they work for Playstation 2 controllers?

Are they of obnoxiously bulky? As in can you feel a major difference in a negative way
