I have cleaned it as much as possible before listing. I also washed the covers. There are some issues, such as the logo peeling off and scratches on the resin parts, but I think it can still be used. Everything is included except for the instruction manual. Please download and check the instruction manual from the following website: https://www.combi.co.jp/cms/combi/images/soudan/after/manual_cp/childseat/pdf/CS_jyoitorip_gc-147926000.pdf?srsltid=AfmBOooy7c60I3AceeohJBQvGidJP3FudwrGr6FcsgtPPGlilymwjhpM For packaging, I will remove the backrest, seat, and drink holder and ship it wrapped in about four layers of bubble wrap, as shown in the last photo. Assembly shouldn't be too difficult, but please check the instruction manual.
