Ohmg! I love this forever pen! It isn't as delicate as my expensive fountain pen and you can use FP inks with it! I thought the nibs were going to be slightly softer and delicate, but they aren't and for that I am glad! The nibs are versatile between the mini and standard, the ink reservoir is also versatile between the two small sizes...I am very happy with my purchase and I am glad I ordered it straight from Tom's Studio vs Amazon. Thank you for the popcorn and extra gift!!!

Lovely little pen

Love Tom’s studio pens. I have brought both Lumos and wren. Love the choice of nibs with Lumos but prefer the barrel width of Wren. I am addicted to changing ink colours. Beautiful to write with and draw with and saving the planet to boot. What is there not to love.

Stock up on these! I have more ink colors than I have spare reservoirs, so I’m going to have to make a special order just for three packs of reservoirs!
