This Arthritis Super Big Fat Pen set (5 pens + 5 refills) has completely exceeded my expectations!
As someone who often experiences pain and stiffness in my finger joints, writing with regular pens used to be a real struggle. But the design of this pen is truly thoughtful — the extra-thick barrel feels soft and comfortable to hold, requiring no tight grip at all. My hand doesn’t get tired or sore even after writing for a long time. The black body looks clean and stylish, and the ink flows smoothly and consistently without skipping. The set includes 5 complete pens plus 5 additional refills — such great value! It feels like it will last a very long time. Whether for personal daily use or as a thoughtful gift for elderly family members with similar needs, this is a practical and caring choice. If you or someone you know struggles with writing due to arthritis, hand weakness, or discomfort, this pen is definitely worth trying. Highly recommended!

No arthritis pain when using these
I bought these for my mother for Christmas but she passed away right before. I had these in a drawer still in the bag for months. This cold winter my right hand began to bother me worse than it ever has had with arthritis. Although I don’t do much writing being retired, I occasionally make notes, do book reviews and write out a rough draft, and write plans in my shop. I was totally surprised on how easy I got grip this pen. Sometimes when I write, I have to use my left hand to adjust the pen in my right hand due to the arthritis. With these pens. I simply pick it up and write. There is no effort gripping the pen and no pain when I do write, I thought that the pen being short would bother me but it’s fine. It’s a amazing how the thickness makes writing and drawing plans so much easier. I have not had one instance where I had to re adjust or stop writing due to my arthritis pain. I bought these for my 86 year old mother, but at 63, they work absolutely perfect for me too. Even though my arthritis is not as bad as hers, it’s just wonderful to write again like I once did with no pain, no effort, and be comfortable. Excellent product.

Nice pen but need refill info--which I now provide
My wife, who has pretty bad arthritis, likes this pen a lot. I don't use it too often but it writes nicely and is easy to handle with my elderly paws. The reason I didn't give this 5 stars, though, is that the manufacturer does not offer refills on this site nor, even more important, identify the refill to be used in product specifications. That would hugely simplify the task of getting more ink for these pens. At least one that my wife has been using ran out of ink pretty fast. Following a tip from another user, I went to OfficeMax to find refills for this pen. They did not have a ballpoint version (out of stock I believe) but the Parker Gel Refill (Quink) fits and works well. But here's the rub: these pens sell for about $2 each here on Amazon.com. The refills cost $3.25 each. So it makes no economic sense to buy refills instead of a new stock of the pens unless the ink in the refill lasts more than 50% longer. That I do not know and while I may be a little OCD, I won't be taking the time to answer this question.

Great gift for anyone with arthritis in their hands.
Thixotropic Super Big Fat Pens were great for arthritic hands, especially if your thumb and fingers are arthritic. It is big enough to grasp easily, without needing much pressure to hold it. I have had these pens before in the clear and black, I love the blue, they are so pretty. I wish that the lanyard to hold it was longer. It easily goes over my head, but it is too short to wear it while writing. It does however work if you want to hang the pen up.

Great tool
I bought these for a coworker who had a car accident with severe damage from the airbag. (Thankful for airbag that likely saved from brain damage). She couldn’t even hold a writing instrument.this did the trick! Made her very happy and now I can read what she writes.

Helps If Arthritis but Replacement Cartridges Damaged
My husband who has arthritis loves these pens. He says they make writing much easier. Ordered a second set for his father. Would give 5 stars but in both orders the replacement ink cartridges leaked and were unusable. Kept the product anyway and tossed the replacement cartridges.

Would give this 10 stars if possible
I’ve had rheumatoid arthritis since I was 12. Now at 27, writing has become way more challenging and my hands cramp up instantly. These pens are fantastic quality. 5 come in a bundle and are already loaded with ink. You also get 5 replaceable ink inserts. They also have removable shoe-string necklace - I could see this working great for people like me who lose things easily. They’re really perfectly for writing everyday notes and I use this for work now. Life changing- no more hand cramps!

Best pen ever - I can write again!
I have arthritis as well as a locked thumb on my writing hand and could barely sign my name anymore. I discovered these pens by accident and am SO very grateful that I did. The design is perfect - comfortable thickness, good grip material. I can once again write! Great value too - 5 pens plus 5 refills! Highly recommend!
