At 16 Euros plus 5 for postage and the extreme likelihood that at least one of the rapiers will break, that's enough reason to go for a sturdier option. If I was a good painter, I might well buy the set for display purposes as they are beautifully done. Sadly I'm no better than average, so it would be scarce funds wasted, I'm afraid.
And no, of course I don't use mallets!
Like all right-thinking people I use 15 pound sledgehammers to perform all my delicate manouvres. After a few whiskeys, my breath can melt resin.
