This blue sheep popit toy is a favourite with kids.  When they feel the need to fidget they can pop the buttons on this sensory toy.  If you have 2, you can use them to play games too. 

They're not just for kids.  Feeling stressed?  Do you like popping bubble wrap bubbles?  This is the eco-friendly sustainable option!  It may not relieve financial stress, but it can help reduce a little emotional stress ;)
