Set of beer crate-style containers for storing and carrying AA, AAA, 9V, and 18650 batteries. Each crate reproduces the classic slatted structure with side handles and shaped internal slots that hold the batteries vertically, separated and tidy. The stackable rim allows multiple containers to be stacked without slipping, so the set stays compact on a desk, shelf, or in a drawer. The dimensions of each crate are 6.84 cm by 5.44 cm. Suitable for anyone who wants to keep spare batteries always at hand, recognizable at a glance by format and ready to use
