All three pieces have battery components, but do not come with batteries. I am not sure what the batteries would do in each piece and I am also unsure if pieces will work once batteries are in. 

Fridge: Bottom of refrigerator door stays closed when shut, but falls off when opening. Fridge door is connected by holes on top and bottom edge of pink door which fit into raised grooves on white part of fridge where they connect at hinge. The raised groove on upper portion of white area has broken off which causes the fridge door not to be able to open and close without the bottom door falling off. Fridge comes with two removable shelves. Water filter has tear in sticker. Pressing filter moves filter up and down. 

Oven/Stove: Slight yellowing around edges of stove burners. Yellowing also underneath upper cabinets near shelf. Rotisserie chicken can spin using wheel. Some discoloration on both sides of rod holding chicken. Oven, drawer, cabinets, and microwave can open. Not visible, but feels like tape residue between drawer and oven sticker. Clear glass of microwave door has small grey foggy patch. Side of furniture piece (the side next to the cabinets) has a mark from old tape. Indentations on back of upper cabinets and microwave. Cannot be seen, but you can feel it. These can be seen with camera flash on. Comes with pot with lid and frying pan with lid. Some scratches of plastic of dishes. Bottom of frying pan has some tape residue and some white marks on frying pan and lid. Pot and lid have mark in plastic. 

Sink: Yellowing on the side of the back - I think this is discolored glue. Yellow dislocation around front sticker with heart and under counter. Faucet sticker torn. Stickers in sink are also not perfect. Mark in sink that looks like sticker residue. Soap dispenser sticker also has imperfections. Black mark and white line on cutting board attached to counter. Dishwasher comes with two removable trays. There may be a missing dishwasher tray for top because there are tracks along side. Cabinets can open. 

I tried to be through in my description and pictures, but please let me know if you have any questions!
