On Amazon, an ivy cube with no stickers is $6.99. A non sticker cube is better, because over time, the stickers can't peel.
The oval piece is the center or ivy piece. The other two pieces are the corners. They are in the shape of a triangle.
This cube actually is extremely easy and if you are a beginner this cube is definitely for you. It has only 1 algorithm and that algorithm has only 4 moves. The first step is to solve the white side with is exceptionally easy whence you get the hang of it. The second step is to solve the yellow side. The last step is to solve the whole cube which is the longest step and only uses 4 moves to solve.
