The inside of the kiln has very few burns or cracks, making it relatively clean for a used item. There are some minor stains and deterioration of the exterior parts. I turned on the power to confirm, and it seems to be functioning properly. The kiln size is small, suitable for firing items like small plates or teacups. As it's the mid-size model in the series, it's spacious enough for accessories and small items. It's being sold at a lower price than the original purchase price, so please purchase without further price reduction. (Photo 14: Purchase data) Photo 15 shows the temperature rise curve. By setting the knob in Photo 16 to the specified number, the temperature will rise according to the temperature rise curve, although it may fluctuate depending on the outside temperature. I don't know anything more than this, so please search online for the instruction manual for more details. Please comment before bidding if you wish to buy it immediately. Although it's only in red letters, I'm happy to lower the price to the limit, hoping it will go to someone who will use it.
