My sister-in-law brought back these lovely diffuser reeds from South Africa. The ornamental ends are ceramic and are attached to bamboo sticks that absorb perfumed liquid. Two proteas and one wheat.
We received three lovely reeds, but it took quite a lot of searching to find the correct perfumed oil. Only difficult, not impossible. I have tried replacing the liquid with a homemade perfumed oil a few years ago, but it was not as effective as the bought product. No faking it this time.
Perhaps some other enterprising artists should jump on this bandwagon.
