This bumper is a piece of rubber that is placed with an adhesive that is incorporated into the surfaces of the drawer where the front cover of the drawer hits. It is made of a special plastic that cushions the blow reducing the noise of the drawers when closing and for greater discretion, it is offered with a completely transparent finish. It is found in two models that have a height of 1.5 mm, but their diameter changes, one has a diameter of 7 mm and the largest has 10 mm. They are only purchased in packages of 2500 and 5000. It is a very useful piece if you want to protect and not hear your drawers closing.
