Love it!

I ordered the pen after I saw a lot of it on Instagram. And I like it! It‘s easy to handle, to fill and refill and it writes nicely. If you are looking for a versatile writing friend, this one is for you :-)

I got more ink reservoirs because I was experimenting with some inks for my lumos and I wanted to have some with different colors at hand!
and my name is Samy. Vincent is my husband :) probably it's Vincent because of the c/o in the delivery address.
THANK YOU for the beautiful tools. Ive been using my lumos everyday since I got it! ♥️

They hold ink, kinda hard to mess that up.
