Rabbit Leak-Free Discreet Flask (Black) – R4-06138 3.25″ x 1.2″ x 6″

received this today. website claims it’s leak proof. Not sure how since it has a snap on top rather than the traditional screw on top I’m giving it four because of size and compact ability. will reduce it to a 2 or 3 of if leaks..update: when I first filled this flask, I was disappointed because it leaked, the flask leaked because I didn’t secure the the cap. since I didn’t see any threads on the neck I assumed it was simply a snap on top, however when I twisted the cap it tightened on the neck and provided a leak proof seal!!?. Also make sure that grooves of the rubber seal is seated securely on the container. Don’t over fill!!! fill only to the bottom groves of the rubber seal .Took it a concert last night!!! and it didn’t leak so I am upgrading my review to 5 stars. good value for the price.
