The 'One Dip Wonder' really is a game changer. Having to dip your pen in ink half-way through writing can ruin your flow, cause an inky mess and take up your precious calligraphy time.  

After months of trial and error I've found the perfect answer to this problem!

 The 'One Dip Wonder' combines the perfect size spring with a tiny but powerful neodymium magnet creating a reservoir of ink for your calligraphy pen

All you have to do is pop it onto the back of the nib (underneath the breather hole) and you're ready to go!  

As you can see from the video it doesn't stop flowing!  

See Milly from @blinklettering 's fantastic review here:


- The One Dip Wonder currently works with larger straight nibs like Nikko Gs, EF Principals, Hunt 101s, Blue Pumpkin etc. (Brause EF is not currently compatible. )

- Please be sure to clean and dry your spring and magnet after each use to prolong their life.

- We have found that the One Dip Wonder will not work with certain colours in the Finetec metallic ink palettes. Our metallic calligraphy inks and Fountain pen inks appear to work well however. Please be aware of this when ordering.

At least double the writing distance

I've been using the one dip wonder with a Flexi nib, which use ink at a high rate when being used for wider lines.
The simple device generally doubles the distance that can be written between dipping.
It's a simple and clever invention.

Fantastic Product so Aptly Named

This product allows me to concentrate on my letters and writing rather than having to constantly dip the nib in the ink. (I consider myself beginner/intermediate and am still learning calligraphy). I did have a slight learning curve in knowing exactly where to position the One Dip Wonder but Tom's Studio has a great intro video and their customer service is top notch in answering any questions. The only reason I'm not rating this 5 stars is probably more my fault in that I always seem to lose the tiny little magnet ball, but after awhile, you learn to work around this too. I recently purchased ten of them because I always want to have one on hand and I keep one with each nib that I use (although you can use one interchangably; I'm just lazy). Great product! I love the One Dip Wonder!

Brilliant little thing

This little metal spring & tiny magnet are brilliant, really does let me write for longer, it's a little fiddly to clean but really worth the effort, I've ordered a few just in case I lose one as I now wouldn't want to be without one on my calligraphy pen

Silly little thing

What a silly little thing, is exactly what I said as I opened my order, But I tried it, and, IT WORKED!!! I could write a lot more than I could without it. It is fantastic and well worth trying. It stays on the nib while you dip your pen very securely.
