Yup! The trick is to fill it half with resin and let it harden before putting your item in, because the item will sink straight to the bottom. I would like to save you some heart ache that I went through.
I have 2 dogs so I totally understand. You do not want them digging in the trash. Just keep it in a sealed place (like a craft drawer) and keep your nose and mouth covered while using it. The fumes can be dangerous. Call me cautious, but I don't feel like killing anymore brain cells anytime soon.
