public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        var product = new Product
        {
            ProductName = "Some name",
            Id = "123X",
            Size = "Big",
            OutOfStock = "true"
        };

        var itm = new ListBoxItem {Content = $"Product Name: {product.ProductName} {Environment.NewLine}" +
                                             $"ID: {product.Id} {Environment.NewLine}" +
                                             $"Size: {product.Size} {Environment.NewLine}" +
                                             $"Out of stock {product.OutOfStock}"
        };

        listBox.Items.Add(itm);
    }
}

public class Product
{
    public string ProductName { get; set; }
    public string Id { get; set; }
    public string Size { get; set; }
    public string OutOfStock { get; set; }
}
