Choosing among fountain pen inks often means balancing curiosity against commitment: a full bottle can be a lot to buy before you know how a color behaves on your paper. The 2mL Kitty Inkpot Fluffy Wool Ball Shading Fountain Pen Ink takes the sample route, giving color-focused shoppers a small format to explore first.
Quick verdict
At USD 6.50, this is an appealing pick for someone who wants to try a shading ink without purchasing a full bottle. The description presents it as a Limited Edition 1 Year Anniversary ink and says it comes in a little plastic vial. That makes the format practical for sampling, swatching, or deciding whether the color deserves a larger purchase later.
The important caveat is the listed condition: Used. That may rule it out for shoppers specifically looking for a new item. The sample format also makes it better suited to experimentation than to anyone who already knows they want a substantial supply.
Product note
2mL Kitty Inkpot Fluffy Wool Ball Shading Fountain Pen Ink

The clearest reason to choose this Kitty Inkpot ink is the chance to explore a named shading color in a small vial rather than committing to a full bottle. Its title also gives the sample a distinct identity through the Fluffy Wool Ball name, while the presentation as a Limited Edition 1 Year Anniversary ink may appeal to collectors of unusual colors.
The limitation is equally concrete: the listed condition is Used. The quantity is also a sample size, so the ink is designed around trying the color rather than serving as an everyday refill on its own.
Who it suits
This sample fits fountain pen users who enjoy discovering how an ink changes across different writing surfaces. The color reference uses Midori MD paper, and the product information notes that the ink may look different depending on the paper. That makes it a sensible choice for someone willing to test it in their own notebook instead of expecting one paper sample to define the entire experience.
It is less suitable for a shopper whose main goal is a full bottle or a larger amount of ink. The plastic-vial format points toward a trial purchase, not a long-term writing supply.
What stands out from the listed details
The combination of a named limited-edition color, shading designation, and sample presentation gives this ink a clear purpose: explore something distinctive before making a bigger commitment. The stated price keeps that experiment specific at USD 6.50, while the Midori MD reference adds useful context for interpreting the color.
Meaningful trade-offs
Paper variation is the biggest practical consideration. A result seen on Midori MD may not look identical on another paper, so the sample should be judged in the setting where it will actually be used. The Used condition is the other major trade-off, especially for shoppers who place a high priority on receiving a new item.
Bottom line
Choose the 2mL Kitty Inkpot Fluffy Wool Ball Shading Fountain Pen Ink if a small, USD 6.50 trial of a limited-edition shading color is the goal. Pass on it if the Used condition or sample-sized plastic vial does not match how you shop for fountain pen ink.
