The 'One Dip Wonder'

$6.00 Sale Save

A game changing ink reservoir. Pop it on the back of your nib and you're ready to go. Buy 3 one dip wonders and save 15%

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.

So so useful!!

I used to snuff at the idea of this little spring thingy that 'steals the joy' of dipping the nib into ink every now and then, but when the hobby turns into a side hustle and getting orders of 40, 50, 100 placecards to write, you'd NEED this little buddy to pull you thru the job without having to stop every minute just to dip the pen in ink!!! I can't do without it anymore.

A wonder to behold!

I have been using a pointed pen for a few years now, for copperplate and for illustration. Having purchased a One Dip Wonder it has made the flow so much better. A simple little device, that really is worth having. And of course the packaging and information lives up to Tom’s Studio’s expected standard.

One Dip Wonder

What an amazing little magnetic spring! It holds so much more ink when I’m drawing with a dip pen. The line keeps going on and on and on. More drawing and less dipping. It’s brilliant.

Probably can use a stronger magnet, but it definitely helps.

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.
