Review on EssShop 3-Piece Set: Purple Glass Calligraphy Pens & Crystal Glass Dip Pen with Color Ink - Ideal for Signatures, Beginner Journaling, Lettering, Drawing, and Gift Decoration - Art Supplies by Summer Hendricks

The coil of the glass pen had a few imperfections, but high enough that it didn't interfere with writing. The best thing I've found about glass handles is that they form a very consistent line. You need to let the ink flow back into the bottle so it doesn't smudge as you write. I will say that some inks work better with it than others. Very easy to keep clean. Save the protective cap and leave it on the pen when not in use. The pen tip is thin enough to break if you place it in the wrong place. The paintwork is good, only one flashing light is present. The little glass cat pen holder is too fragile to be really useful, but it's cute. Good and elegant packaging.
