I have had many cusotmers over the years ask for this type of item but I could not find them until now.  Check these out.  They are 200 series stainless and they have been polished so they are close to a mirror in their reflection characteristics.  The shell is only 0.5mm thick.  It would be great as an ornament or decorations.  I like it for buoyancy experiments.  It is cool to see something so light weight displace so much water.  Check them out.
