Product: Deadstock Sanrio Kitty Helium Balloons - 30 Balloons - 1999 Heisei Retro Event Party (Size) Diameter: Approximately 38cm (when flat) These were deadstock items found at a relative's house. I believe they are helium balloons for events. There were 3 bags, each containing 10 balloons. I opened them to check their condition and take photos. In images 15 and 16, there are some with minor print peeling. Therefore, I have marked them as "Like New." Images 18 and 19 are sample images of the balloons inflated. The items being sold have not been inflated to check. There are also paper weights (like in image 12) for the number of balloons. They were held together with rubber bands, which have deteriorated, leaving marks as seen in images 13 and 14. I will fold them to the size in image 17 and ship them in a separate OPP bag via Yu-Packet Post. I am not currently considering selling them individually. I would prefer that you purchase all 30 balloons together. Although they are unused, they have been stored for a long time, so please refrain from purchasing if you are overly concerned about their condition.
