Both have distortions in the rails. Also, one has a broken protrusion on the connecting part, and there are cracks due to the distortion, so please consider it a junk item. I cleaned the details with disinfectant wipes when listing, but since it is a used item, please understand that there may be some minor scratches or scuffs. [About packaging] Packaging will be simple, with waterproofing in a plastic bag and then placed in an envelope. If you would like careful packaging with bubble wrap for delivery via Takkyubin Compact, it will be an additional 300 yen. Please comment before purchasing.
