COMMON QUESTIONS
Can your pens be used with a cartridge?
Our pens are designed for use with an International Standard converter but are also compatible with International Standard and Short cartridges. Remember to manually push the cartridge into the grip section to puncture it properly.
Can your pens be eye droppered?
DISCLAIMER: Converting non-designed fountain pens to eyedropper ones is at the user's risk. Our 100% resin pens can be modified this way using silicone grease and a specific rubber o-ring for sealing. Wood pens are not suitable for this.
If I eye dropper my pen, will the ink stain it?
For our testing we used Lamy Blue/Black ink. It did not stain, though we did not do a long-term test.
Most standard, water-based inks should not stain the resin. However, some highly saturated or pigmented inks may tint or stain the pen, particularly the lighter-colored resins. When in doubt, look it up—there are likely posts and reviews online regarding the specific ink you are wondering about.
What resin so you use?
We use Alumilite urethane resin, which is made in Kalamazoo, Michigan.
The colorway I want is sold out. Will you be making more?
The small batch nature of our pens doesn’t mean we won’t make more of a colorway. Feel free to reach out and ask us about the specific colorway.
Do you do bespoke custom orders?
Yes. Please email us at info@redbranchcrafts.com for a consultation.
