These have been a bestseller of mine for years.  Fabulous colours in a versatile long loop that can be worn looped twice or three times around the neck, or even converted to a v-shape with a drop by threading one end through the other.  Made of dyed coconut shell, they are beautifully smooth and tactile as well as super-light, making them comfortable to wear and easy to pack.  This one is a bright electric blue – gorgeous with a white shirt and jeans. 

Ethically made by a social enterprise in the Philippines.  Coconut shell beading. Approximately 78cm drop.
