Big surprise when opening the sachet, the bands do not smell. Not a bit ... you just have to be introduced already in the nose to sniff out what. I've never experienced at any Loombändern. Furthermore, they are very well made and regularly. Test rubbers were very stable (no baggy) went even after "overstretching" back to the original shape and cracks only by force.
The lights could be a little more intense.
I would order them again, unfortunately the seller has it at the moment probably not in the offer.
