Beautiful Blue Swirls float with tons of bubbles that really adds to its visual appeal.

This float has a seal button that's made out of light green glass.  This is commonly called a 'green eye'.

There's a pretty clear 'l' stamped on the seal.  It's not a cursive "1" but more like a hash mark.  None-the-less, I'll call it a WP #80.

It also has an inclusion that could be a small kiln stone.
