Question about Roline Screen cleaner

Would it be possible to buy just the microfibre paste without the accompanying bottle? It's by far one of the best pastes I've tested, but spending CHF 35 when I'm only using the paste (I already have two bottles at home) quickly becomes restrictive. I'm also open to suggestions from other brands offering microfibre pastes that are really effective at cleaning screens, and not just moving stains around.
