If you are looking for the very best bath sponge, then you want a Rock Island Premium Sea Wool Sponge. Processed naturally, and brought to a gorgeous golden yellow color, these sponges are soft as silk when wet, and extremely durable. There is no finer bath sponge on earth! We recommend the FORM (whole sponge) if you want larger premium sponges. Cuts are great if you want that sea wool sponge, but smaller and less expensive than the FORM. To give you an example, if you cut a 6" FORM in two, you would have 2 5" Cuts. Both are amazing sponges, but its about preference, shape, and size on which you choose.
