We Are A Worldwide Supplier
I am proud to be probably the only web site supplying pen spares all made on site by myself, and the ONLY source of genuine Onoto plunger washers
We allow you the customer to change the exact dimensions of some of the parts I make to your requirements. Simply select the part required and using the customisation details at the bottom of the page, insert your preferred dimensions... Don't forget to save your changes and I will manufacture to your request.....simple.
Most of the parts are ready to post, but if there is a stock issue I will contact you with a delivery date when I get your order.
I have now added a tag to allow customer comments for each product. Please feel free to use the feature.
If you have a part you need but cannot see it in a list, please mail me at
or use the CONTACT button below.
I am always interested in your comments. Feedback is important to me
