After all these years, the Sunderland mk1 remains my favorite machined pen of all time, and I’m pleased to announce that we now have more of our exclusive design on their way, set to arrive next week. This was our first store-exclusive pen, initially released back in 2021, and I’ve always intended to bring in more, though for many different reasons it’s taken longer than originally hoped. The T.G.S. x Sunderland mk1 features a bead-blasted, matte black finish with a bead-blasted DLC-coated clip. The section is a matte red/burgundy, with the overall color scheme designed to evoke the T.G.S. core colors burgundy & black. While you can read more about the specs of the Sunderland mk1 in our full review of this pen, what I truly love about it is how well the pen posts, and the contoured grip. The internal threads are recessed into the nose cone of the pen, so they will not interfere with your writing.
Despite three years having passed, and costs having increased, we’ve managed to keep the price of this edition close to the original. The T.G.S. Sunderland mk1 will retail for $115, which includes U.S. shipping. All pens ship with a Pilot G2 refill. You can pre-order today, with the pens currently set to arrive mid-to-late next week.
Note: If you’re an international buyer please review our shipping policies, including our UK order threshold. If your country isn’t currently listed on shipping options when you try to check out, please contact me through the site and I will see what I can do.
Refill Options for the Sunderland mk1
While the Sunderland mk1 was designed to accept Pilot G2-style cartridges and the Montblanc rollerball and fineliner cartridges, with a little hacking I’ve been able to fit multiple popular refills in this pen, including the Pentel Energel, the Zebra JF (the Sarasa Grand and Sarasa Grand Vintage refill), and the Uniball One refill, all of which require a small spacer at the back of the pen. I use a small piece (3-4mm long) of plastic aquarium tubing, though you can also use a small folded/wadded piece of paper, or wrap washi/masking tape around the end of the refill to increase its length. (Yes, I know there are other many “guides” and lists of “compatible” refills, but I try to only list those that I have personally tried myself.)
If you have had success using specific refills with the Sunderland mk1 pen, please drop a comment below so that I have a list of new refills to try. This is actually a very versatile machined pen, but since they are made in small batches they often don’t get as much attention as they should. Let’s change that!
