These natural birchwood knives are a great choice for your events. You can use them at banquets, picnics, or outdoor parties. Just pick up a knife and use it like you would any other utensil. When you're done, you don't have to worry about washing them as they are single - use. Remember, do not put them in the microwave or dishwasher as they are not safe for these appliances. Also, keep them away from direct heat to prevent damage. After use, since they are biodegradable, you can dispose of them in an eco - friendly way. They come in a pack of 100, so you'll have plenty for your guests. And unfortunately, there are no returns or refunds, so make sure they're what you need before purchasing.
