Features: One of the immediate features of our storage grid pad is their ability to keep items stored on them dry. This contributes to the durability of your stored items, especially in damp environments. The floor pallets's round hole grid design allows for free air flow. This is key in promoting the longevity of perishable goods or goods that require specific storage conditions by maintaining a constant flow of air.
