Lid: Lid: Bamboo, Transparent Nitrocellulose Lacquer Packing: Silicone Rubber Designer: Sarah Fager] Thank you for viewing. I don't use it for making sweets, cooking, storing ingredients, or serving directly at the table, so the heat-resistant glass is a waste for just freezing cakes, and I've been using a novelty container I received afterwards. After using it once, I put it back in the bubble wrap bag and stored it in the cupboard for about 2.5 months, and I think it's in a clean condition. It seems to be a product used in hotels and sweets shops. There is no weight listed in the description, and when I googled it, the AI answer was: 1.0L (21x15x6cm): Approximately 0.68kg (body + lid). For those who understand that it is USED, please consider. Shipping in a 60-size cardboard box. (It fits perfectly in a Yu-Packet Plus dedicated box, but it's difficult to increase the thickness with more than ⑥ layers of bubble wrap, so I'm using Takkyubin (home delivery service). If you wish, I will discount it by 200 yen, but it will only be wrapped with paper etc. around the body and the gaps on the sides will be filled to secure it. It doesn't seem to be a fragile sticker-applied delivery service, and the glass is thick and heavy, so the Takkyubin price is displayed.) I apologize that it will be a bit expensive as a single item due to shipping costs. I am also selling other items, such as a new ceramic round storage container with a lid and a new, half-capacity heat-resistant glass container with a plastic lid. → Since this IKEA item hasn't sold at the single item price, I will relist it as a set of 3 when I have time.
