1. A sliding sleeve for use in a casing string comprising:
a. an outer tubular member with one or more treatment ports, wherein the outer tubular has an indention to receive an inner tubular; b. an inner tubular member that is slidably engaged with the outer tubular member and is shorter than the indention in the outer tubular, such that when the inner tubular member is in an open position the one or more treatment ports are open to the interior of the inner tubular member; c. a sealing element between the inner and outer tubular members, wherein when the inner tubular member is in a closed position the one or more treatment ports of the outer tubular are covered by the inner tubular member and closed to the interior of the inner tubular member; d. wherein the inner tubular member has no feature that is engagable by any tool other than a gripping tool that exerts pressure radially outward directly on the inner tubular member.
