These are rare, larger-sized organza drawstring bags. The size is approximately 25cm x 35cm, about the size that can fit A4 paper. The color is white, and this is a set of 30 bags. I purchased them for gifts but had extras and stored them in a box. When stored in the box, I folded them in half, so there are fold lines. When you put items inside and cinch the bag, I personally didn't find the fold lines to be very noticeable. How about using them for prizes or gifts? These are used items that have been inspected and stored by an amateur, so please only purchase if you understand this. They will be shipped folded, so please be aware of this. Also, as they are made overseas, there may be variations in size, so please consider this before purchasing.
