Is there a trick how to put the rubber bands of the flipper fingers. I have to be very brutal to get them over the flipper finger. Im scared to kill my flipper fingers with brutal man power. Make them warm could help. But Im scared that this will make them too stretched and they didnt go back to their strength as they are when they are new. Does someone have tip for me? Otherwise I will warm them up. They are the original ones and have to go over it more easily

Thanks a lot for your answers. Did the finger stretching method now......it goes a little bit easier. I will try it with warm water in future too. I think warm water method will help a lot
