What Is An Egg-Safe Pen?

What kind of pen or marker is safe for writing on eggs? Or is the better question what ype aren't safe?

I use a pencil on Crestie eggs.

I am of no help but am interested in the subject;):D

I've used a sharpie with no ill effects.

Pencil works great and doesn't 'bleed' all over the egg

I've always just used a pencil on ball eggs. Plain ol no. 2. No ill effects.

Never wrote on reptile eggs but have seen sharpies kill chicken eggs but pencils work with no problems

I have used sharpies on leopard gecko and corn eggs with no ill effect. I'm planning on using them when my ball lays, but I won't if it might be harmful.

+1 for the blunt pencil brigade. :)
