【Purchased at Amazon Late Last Year】 The feet of the suitcase were made of Samsonite's sturdy, unbreakable material, so I tried sawing them with a saw several times, but gave up in seconds and decided to list them. ※ I wore gloves when I held the tires, so they got a little dirty. ◼︎The last 3 images are actual photos. There is dirt on the rubber gloves, and some of the blue from the rubber gloves has transferred to the instructions.
