I don't know about the rest of you, but lately I've been finding myself saving different size glass jars to store the small rocket parts and building materials. They are great for a lot of things and since they are glass it allows you to see exactly what you have. I have one jar full of center rings for MPR and another for stirring sticks for epoxy and another for CA glue, which I keep in the frig to extend the life and keep it from going bad. Not sure how many of you have Costco's in your area, but they sell a 3 pack of peaches and the jars are large enough to put almost anything in? My other hobby when I have time is nitro RC SCT's and I was going to save coffee cans for soaking parts and I'm sure you can, but the lids are plastic don't last, but a glass jar works great! Just like the Midwest Aero gloss Sanding Sealer, which you can't get anymore. Those small jars are great for snap swivels and other small items. Save your jars
