 Paper ones sometimes contain a sterilizing agent such as alcohol or stabilized chlorine dioxide.Paper "oshibori", unlike cloth "oshibori", can be folded and put into a very thin plastic wrapping for inclusion with packaged products such as bento lunch boxes in convenience stores.An "oshibori" can be moistened with hot water at an appropriate temperature or steam to make a hot "oshibori", or placed damp into a refrigerator to make a cold "oshibori" suitable for use in summer.
