Abstract
Abstract A flat transparent slip is formed with an integral handle part, including a prong that rises from the slip and has with the latter outside the confines of a growth area thereon a joint with a constriction for ready snap-off of the handle part from the slip. In another form, a number of slips are arranged in a cluster with an integral handle and so that any slip may be snapped off the handle.
