The Glass sucker lifter/Vacuum suction cup comes in a box with a pair of gloves and other accessories needed.It was so easy to use, just press the pump bottom a few times until the red line disappears, it will stick on the surface of glass or marble tightly. impressed with the strong suction.Ideal for moving glass or tiles, you might need two of them to finish the job if the item you want to move is big.Overall I am satisfied with the product and would recommend.
