All silicone Sink rack is covered by Silicone on the stong steel x-frame.
Silicone is non-slip, preventing from being moved back on a slippery surface.
Rolling sink rack is good to dry off dishes or vegetables,
and stable enough with its stong steel core and the middle silicone band ( 2 bridges) for additional support,
which can stand big or heavy objects. At the edge on one side, you can also put the small ones that might fall out in the middle like chopsticks or cherry tomato.
This item helps dry off things, and can be easily stored as it is rollable after use.
Make sure to avoid placing a pot, extremely hot or too heavy and keep away from flammable or ignitable substances,
which can pose heat damage or burn hazards.
