    These WNA Comet Classicware EcoSense 7 1/8" Biodegradable Heavyweight Black Plastic Knives are awesome . What a great product! Great price! They are shatter resist. We will be purchasing more of these in the future.
    Theses are made from biodegradable material and yet strong! We would recommend this product! We gave 4 stars! And it's come in 7 1/8 inch size!
    For our wedding, I wanted to keep almost everything eco-friendly. This cutlery was sturdy and looks nice. I know it will hold up well for pizza and salads at our food truck wedding!
    I was hesitant to try these as I have found biodegradable tableware in the past to be flimsy and break down easily, almost getting soggy. That is not the case with these! These knives are just as sturdy as their plastic counterparts and the black color makes them look a bit nicer. I highly recommend!
    Very sturdy plastic knife. We have started using these with all of our 2go food items. One of the first plastic knives we have purchased that does not snap while applying pressure and cutting food items. Also these are priced very well.
