Great little gift for a new rider to spice up their ride! Can't vouch for their durability or functionality yet as they are built on a 'summer' car but for the price they are easy enough to replace if needed.
Pros
Premium Material: Valve stem caps are made of high quality aluminum alloy and handles are made of high quality plastic. These heavy-duty valve stem caps are airtight and dustproof, strong and durable without worrying about splitting.
