Bananacus

Bananacus is a sliding-bead puzzle. It has two segments from the Quartolabacus puzzle and two ends.
The object of the puzzle is to scramble it by changing the shape and sliding the beads,
end then try to solve it. The puzzle is not too difficult, as there are only two colors of beads.
Brainwright markets the Bananacus as "the potassium packed puzzle". https://www.brainwright.com/products/display/8019D
