The Jarware Mason Jar Piggy Bank in Blue transforms any left-over canning jar into a super-cute piggy bank. BPA free and made of recycled materials, the lid is dishwasher safe for easy cleaning. Use a bit of  force to snap the lid on, and start collecting change. The bright blue lid features a cute coin slot as the mouth of the pig. If seeing your change and bills collect is incentive for you to save, this is the perfect way to do it. Remember, you need to supply the Mason jar. Use a Ball, Kerr, Kilner or Anchor Hocking 16 ounce jar for the best results. This Mason jar accessory fits regular mouth jars only.
