Body "tappers" - for stress management / sauna

A tool made of bamboo, which you can "tap" on the body. Widely used in massage and Chinese medicine. We use it in our yin yoga classes and we also offer it for rent in the sauna. Some claim that it removes stress and increases circulation (we agree). Since it is about 50 cm long, you can also use it on your back. It is also nice to take "first thing in the morning" to "wake up" the body.
