Review: They are rubber corks meant for science, but we used them for something different. In building a portable solar generator (DIY Goal Zero Yeti 400) I was trying to find a way to secure the bettery inside of the plastic ammo box used for the generator housing to attach everything to and needed a way to protect the battery from the screws protruding in from attaching things to the outside of the box. I screwed the charge controller and inverter on opposite sides of the box and used these rubber pieces to screw onto the back of the pointy end of the screw inside the box. This worked great not only to protect the battery from the screws, but they also happened to be the exact right size to where the battery slips in the box, snuggly right between the rubber bumpers with no modification using a 396wh battery. Sometimes you need to think outside the box and this worked perfectly for what I needed them for!

This is a great product but the description says 1 pound/ 50 count bag of stoppers. It doesn’t say 1 pound OR 50 count. Received 36 stoppers.
