This is a review of the SumDirect 100Pcs 4x6" Sheer Drawstring Organza Bags.Each bag is 4x6 inches or 10 x 15 cm. (L X W)Size:Approx. 4 x 6 inches / 10 x 15cm(L x W)Summary – Using these for something not quite normal which is to make bags of silica gel using a 5lb bulk quantity and I am very happy with them. I use silica all the time for storing electronics, hard drives and to keep my guns and items in my safe moisture free.When I used a free online silica gel calculator, it shows I would need 238grams for a one cubic foot area. I then convert that to ounces, fill one of these bags on a scale to desired amount and all done.In terms of the bags, after researching I found organza bags are the best for this need as they are very sheer, hold a good amount of silica and are easy to tie off and reuse. Plus with the quantity of 100 for such a low price, not sure I would ever run out.As with all my reviews, I will update this review should they develop any issues with ongoing used.
