Damages:
It's important to inspect the packaging of all items upon arrival and ensure all boxes listed on the delivery receipt are received. If you notice any damage or missing packages, make a note on the bill of lading, take pictures & videos, and refuse delivery. The note should state "refused due to damage."
If there is no visible damage before opening the box, note "subject to further inspection, may contain concealed damage." By signing a freight delivery without noting any issues, you accept the product as-is and release the seller from liability.

We cannot process your claim if images & videos are not provided within this timeframe. Once we receive your information about the refused delivery or concealed damage, we will initiate a claim with the shipping company or manufacturer and ship replacements at no cost to you.
