Reusable straws and carrying case

My kids are very in to saving the planet and the wildlife, so I got my daughter these reusable straws.  With the case, she can take them in her purse and refuse the plastice ones that they offer in most restaurants.  The case keeps her purse from getting sticky.  There are 4 stainless straws and 4 silicone (food grade) straws.  They come with "stops" so your straw doesnt slide around and can lock into most of the reusable glasses.  There are also silicone tips for little ones to adapt to using a straw.  There are also 2 brushes designed to help clean the straws while washing them bacause just rinsing them after a milksake or thicker drink might not get everything out.
