Euroscrubby (pack of three)

Are these compostable?

A website saya these are made of "micro fiber"; isnt that the material used to make fleece jackets? If so... isnt that just recycled plastic?

I’m looking for the EuroScrubby that’s cloth on one side, is this the right one?

Is it possible to request certain colors or styles? Do they look exactly like the three pictured?
