These propellers are very light and thin, similar as GWS propeller. Extra features is it really glow in dark, if you keep this propellers in front of any florescent light for 10 to 15 sec and then switch of light you will see it is glowing into dark, however this won't last more than 60 sec but still it is nice features. I have uploaded one picture in file tab so that other people can see.
