Natural wooden speaker that has no need for cables or electricity. It will give a warm and nice sound just by placing it there. 
A good match for outdoor use since it doesn't need any battery or USB power source. 
This speaker is made of rubber wood (also used for furniture and interior goods), a natural material that reuses the wasted wood after natural rubber is extracted from the trees.
*Since it is made of a natural material, the printed part may be affected by the grain or shape of the wood.
