Quick verdict
Choosing between small fountain pen ink samples usually comes down to two practical questions: which color do you want to try, and how much does the sample cost? Lennon Tool Bar Sesame Oil and Troublemaker Moon River share the same basic format, but they offer different named colors and slightly different listed prices. Moon River is the straightforward price pick at $3.75. Sesame Oil costs $3.99, making its case primarily about preferring that color.
At a glance
| Ink sample | Ink color | Format | Listed price |
|---|---|---|---|
| Lennon Tool Bar Sesame Oil | Sesame Oil | New, 3mL mini plastic bottle | USD 3.99 |
| Troublemaker Moon River | Moon River | New, 3mL mini plastic bottle | USD 3.75 |
Both are listed as new ink samples made of ink and packaged in the same 3mL mini-bottle format. The listed price gap is $0.24, so color preference is the more meaningful separator for many shoppers.
Where each sample wins
- Lennon Tool Bar Sesame Oil: the better fit when the Sesame Oil color name is the reason you are shopping, and the extra $0.24 is acceptable.
- Troublemaker Moon River: the better fit when you want the lower listed price among the two or specifically want the Moon River color.
- For trying a small quantity: neither has a format advantage here; both are listed as 3mL mini plastic bottles.
Product notes
Lennon Tool Bar Sesame Oil

Lennon Tool Bar Sesame Oil makes sense when the named Sesame Oil color is the deciding factor. At USD 3.99, it is the higher-priced sample in this comparison, with a $0.24 gap over Moon River. That difference is small in absolute terms, but it still matters if you are building a group of samples and want to keep each purchase close to the lowest listed price. The sample arrives as ink in a 3mL mini plastic bottle, which keeps the format focused on trying the color rather than buying a larger bottle. One limitation is that the description cautions that the actual color may vary slightly because of lighting and screen differences, so the displayed impression may not perfectly match the ink you see in person.
Troublemaker Moon River

Troublemaker Moon River is the practical choice when the Moon River color is the one you want to explore or when the lower listed price matters most. At USD 3.75, it sits $0.24 below Sesame Oil while keeping the same 3mL mini plastic bottle format. That makes the sample useful for a color-first purchase without paying the higher amount in this pairing. Its limitation is not about packaging or material-the two samples match on those points-but about color expectations: the description says lighting and screen differences can cause slight variation in the actual color. If you are choosing based on a very specific visual impression, treat the Moon River name as the selection cue while allowing for that stated variation.
Final choice by use case
Choose Troublemaker Moon River if your priority is the lower listed price, with the sample priced at USD 3.75, or if Moon River is the color you want to try. Choose Lennon Tool Bar Sesame Oil if Sesame Oil is the more appealing color name and the USD 3.99 price fits your plan. For shoppers deciding mainly on format, the result is a tie: both are new, 3mL ink samples in mini plastic bottles. The final decision is therefore best made by matching the named color to your intended writing experiment, then using the $0.24 difference as the tiebreaker.
