I used these to rubber band the leaves on my daffodils - something I do every year to permit the foliage to "ripen" while rebuilding the bulb. I don't put the rubber bands on tight because I don't want to destroy the foliage just neaten up my garden. These lasted about 2 weeks outside and then started to fall apart. I've used other "economy" rubber bands that are better for this job. So not my favorite.
