10 Pcs Transfer Bearing Roller with 2 Holes, Universal Castor Balls with Nylon Ball and 16 Pcs Screws for Transmission, Furniture, Wheelchair

Bought these to put under a small set of storage ottomans/children's toy box (2).Items arrived quickly and were well packaged (not overdone and in suitable small for safe storage if all wheels not used).The wheels are small and were a lot smoother than alternatives.The profile is also very low and gives the impression that the item the wheels are attached to, is on the floor (especially on thick carpets).The included screws are a welcome bonus and effective.Overall they are lot better than the larger metal alternatives which make an absolute racket, and lifts the item much higher of the floor. They also do not weigh as much as the metal ones.Time will tell as to the durability - bit 5 wheels under a box full of kids toys should last a long while.
