Used IF jars are fantastic...smallest size for boat papers, licenses and extra $10 emergency fund.
Bigger sizes for plastics like Beavers...add a teaspoon of your favorite scent, gently shake 20 seconds and drop in a boat storage box.
Also useful in your bait prep room for hooks and whatever...ask a couple of buddies with kids to save them for you...in 2 months you will have a lifetime supply. Many many uses...they float and have red caps too. I like.
