This is a custom puzzle, handmade by me, weighing in at 204 grams, measuring 11 x 8 x 6 centimeters.

It has interesting bandaging which makes the puzzle quite tricky to solve, which, along with its shape-shifting properties, interesting stickering scheme and blocked moves from overhanging pieces, make this quite a challenging puzzle.
