And so it is with the coveted coastal treasures that wash ashore during low tides all over the world, known as sea glass. Shaped over many sunrises and sunsets, these bits of colored glass drift for as many as two hundred years, weathering storms in the salt water, tossing and turning, Mother Nature’s own polishing that gives them their characteristically smooth, frosted texture.
Prominent in the Northeastern United States, beaches along the shores of New Jersey and New York can be found teeming with these heirlooms and artifacts of whiskey and spirits, trinkets, medicine bottles, dinnerware, jam jars, old taillights and if fortune finds you, a piece of an antique ink bottle.
First used decoratively at the turn of the last century, beachcombers seek out these little gems giving credence to the statement that one man’s trash is another man’s treasure. A bounty of colors ranging from amber to green, black to pale pink and clear frost to the rarest turquoise blue, make sea glass a highly collectible commodity.

Simply unscrew the end cap, dip into ink, screw back the end cap, and your done! Ready to write!!
Pen cap has an inner cap to insure a perfect seal when stored away.
Made for the beginner who just wants to try out fountain pens, all the way to the experts. A good everyday worker.
Please note: Ink is NOT included
A quick no brainer guide in choosing nib sizes in an overly complicated fountain pen world:
If you write small, go with an EF
For the normal writer, F is the most popular
If you tend to lean on a bigger font, M will be perfect
B is for statements!! Sign a check in B, write a header in B, do some coloring/shading in B
Stub nibs are italic in writing style (have a special card or invitation to write?)
