What are your favorite plugs made out of?

I have a pair made from a cow bone that a friend made for me, I love them!

My favorite plugs are made from bone, but I also love the ones made from glass.

My favorite pair of gauges are steel with opals.

My all time favorite plugs have got to be these little buffalo horn double flares I got at my last renaissance festival. I have psoriasis that flares up pretty bad sometimes, but every time I stretch it makes the spots behind my ears even worse (I think I also have an allergy to the acrylic tapers). But once I put these buffalo horn plugs it I noticed a dramatic difference! It cleared up so fast! And the they were so easy to take care of and keep clean. Definitely sticking to the natural plugs!

I love plugs made of gemstones, like labradorite, but alot of people on here say wood, I guess I need to try some wood! :)
