So what's everyone's opinion on very simple, fabric covered boffers like this?

A lot of people at our local LARP requested what's basically function-over-form boffers. Something that's extremely light and easy to handle. Also cheap.
So this is what I came up with. Carbon fiber core, ultra light camp map foam, covered in stretchy fabric. All shaped and colored to at least make it look like a cartoony blade.

Decent compromise, or nasty immersion breaker?
They sold like hot cakes, but I'm wondering if I can improve them somehow. The ones in the pic were dagger sized. I also made sword sized ones with a longer blade and hilt, but forgot to take pics...
