Hydrologic has developed new packaging for the CWP and rebranded the unit "Super Tunsai," (i.e. super rabbit) which features a shiny plastic holding case. The technology is identical to the standard CWP Tunsai in all ways except for packaging. Hydrologic sells the super Tunsai for 23.50 USD and the classic Tunsai for 13.50 USD, while the difference in m anufacturing cost is only 5 dollars different. Hydrologic claims that the Super Tunsai model sells better because it is associated w ith a higher social status and is more readily distinguished from aidbased handouts from the Red Cross and others21.
