A fun maze game on top. And a magenet to hold the top 2 parts together.The rest threads open. Made of pretty colors too. Made of metal so the teeth don't break.Put the dry herbs in the top and twist. The holes are the right size to let the ground herb fall thru. Then seperate your grinder and empty the herbs. #Rankboosterreview #Sponsored #Eschone https://www.amazon.com/Eschone-Grinders-Colourful-Magnetic-Valentine/dp/B078NXXGJL
