Size approx 6-8cm by 25cm. It is used for mounting of orchid. For those orchids that I sell that are growing in pot, I can help you to mount them onto bark upon requested.
Orchid grows on bark will usually be very healthy. And in my word, it almost won't die. A hanging orchid exhibits the beaty of nature.
Minimum of two pieces for buying fir bark along.
Larger size are also available ...
