Used indoors at home only. Never used outdoors. I'm selling because my home no longer uses gas. The hot sand cooker has been used less than 10 times, but please check the images for any scratches. When you make hot sandwiches, the TSBBQ pattern is stamped on, making them very stylish. The grilled rice ball maker was used about 1 or 2 times. Please understand that these are used items before purchasing.
