Lockum’s new style license plate “Rotating Tumbler Boobs” are not soft and fragile. We want to show you the best license plate security device ever invented. Once installed your “Rotating Boobs” will rotate 360 degrees around and around. Your existing license plate attaching screws are safely hidden inside and out of site. Our U.S. Utility patent # 9,914,411 was issued on the complex surrounding this product.

Unlike “security screws” there are not any holes in which a thief would be able to force a flat screw driver or a pair of needle nose pliers into the head of the screw, and this is a big problem with most security screws.

Notice that our “Rotating Tumbler Boobs” don’t have any “holes” on the face for unwanted removal and made in the USA out of heavy aluminum metal. When you order your product it will come with instructions plus spacers and two different accommodating tools.

You may order the “Rotating Tumbler Boobs” with or without the license plate frame that is displayed or you may order just the “Rotating Tumbler Boobs”.
