I used this for smoothing out wrinkles in leather when making shoes and bags. It didn't come with a socket, so I used it with a spare light bulb socket (E26 base) that I had. The socket is not included, so please prepare your own. It heats up very quickly after being turned on, making it convenient to use right away. Besides smoothing wrinkles, it's also useful for shaping edges, heels, and core materials. I am also selling other items related to shoemaking. I will offer a discount to those who wish to purchase multiple items, so please feel free to inquire.
