used them when #1 daughter moved and put her stuff in storage. It's been 2 years almost, and they are still in storage holding up. Can't imagine what they will smell like, but they were packed with clean linens, towels, etc. and a dryer sheet as recommended. They look fine last time we checked them. AND we live in upstate NY, so they have been in a cold storage locker and been frozen. Interesting they didn't "pop"
