I have a LOT of patent bags which I've owned for years. So far, so good. No shine loss, no trouble with color transfer (though most of my bags are bold or dark colors- I bet you won't have any trouble w/paprika. I have a coral patent Zoe that looks similar to this paprika, and I've never had trouble).
I know light patent tends to yellow with time, but have found that my camel patent bags (MSB, sabrina) have aged extremely well as long as they're kept in their white dust bags and out of light (both in closets).
