TWSBI made a name for themselves with their high-quality, affordable demonstrator pens, which let you see the inner workings of your pen. The built-in filling mechanisms they use are usually only found in much more expensive fountain pens. TWSBI encourages writers to get to know the mechanics of their pens by disassembling and maintaining them at home.

Local Area Delivery
For customers who live within three miles of The Paper Mouse, we offer local area delivery services when you make a purchase on our website.
Customers with eligible addresses will see a local delivery option at checkout when placing an order online. Delivery has a flat-rate fee of $5. Orders will be delivered after 5pm on the next business day after the order is received.
International orders may be subject to import fees, duties, or tariffs that are determined by the country of delivery. The Paper Mouse is not responsible for these charges, nor are we able to calculate them prior to shipment. We advise that you work with your local Customs office to determine these charges prior to placing an order.
If a shipment is refused due to unwanted fees, duties, or tariffs imposed by Customs in the country of delivery, you will be charged for both original and return shipping, as well as all associated fees.
Please understand that delays due to Customs processing are out of our control.
In the event that an item you purchased becomes backordered, we will attempt to contact you to see if you wish to exchange with a different item or receive a refund.
