and that changes the usual colors. the couleus are slightly fluorescent (light neon, no bright color) but not phosphorescent as suggested by the picture .. so NO they do not see in the dark or when I had a defective batch. the - there is no label impossible to know if it is latex or not. However, these elastic are flexible, easy to work and do not crack. no elastic in poor condition in the received packet. shipped from China so long delivery (4 weeks for me) but given the great price .. in the package there was also a note of thanks ... nice!
some reviews say that the colors are too "girls" or that it smells oil or they are scented !! for my purchase colors mixed well and no smell. This may depent batches ??
July 2014. My children made me one of those famous bracelets with these elastic and I had an allergic reaction eczema wrist .. by against them have nothing.
