Glass pen with a blue and red gradient.

I bought this on my recent trip to Italy. It is made in Italy. I did a test write to check the thickness. It has a slightly thicker impression of about 0.8mm. I think it can be adjusted using fine sandpaper and water for the pen tip.This is a single glass pen and does not come with a box or anything.It is a transparent glass writing instrument with a pen tip that is about 0.8mm thick.- Color: Transparent - Pen tip thickness: 0.8mm - Material: Glass - Design: Wave pattern ink sample - Use: Art, letters Made in ItalyThank you for viewing. excellent for everyday use. top-grade materials and excellent craftsmanship ensure long-lasting durability.
