This item is 1 oz. or 400+/- approximately 4mm x 3mm Mixed Colors Glass (size 6) Seed Beads. Our current mix has more colors than the photo above. We are always adding new colors. These are not A Grade seed beads, but they aren't priced as A Grade either. So, yes these are B Grade at best. You will get plenty of decent beads in this mix with some possible cull. We put more than 1 oz in our "1 oz" bags to make up for this. 1 oz = 28.3495 grams Any questions just ask. Many More Items Coming Soon from Alice's Looking Glass Jewelry!!!
