They are long enough so that Darby can still throw back her juice like she does -
... and when she gets in her silly "uh oh" throwing mode, the sippy or snack cup is only going to go SO far! It doesn't hit the floor so there's no getting dirty, and she can pretty much pull it back up herself.
I never expected to come across such a find at a drug store. This was definitely a diamond in the ruff!
I'm sure I could even figure out a way to make these simple straps myself, maybe I should! Whoever had this idea is one smart person!
