Eyepiece for Field Scope GL80 Used

Used eyepiece for field scope, GL80.
This was included in a set of astronomical telescopes I purchased used. Based on the model number, I believe it is an eyepiece for Vixen field scopes, but since I do not own a Vixen field scope, I am selling it. Please confirm compatibility with your model.
For Vixen GL80, please refer to the manufacturer's website.

[Items Included]
Everything shown in the first photo is included. (Main unit only, no front or rear caps, etc.)

[Condition]
I do not own a compatible field scope, so details have not been confirmed.
Subjectively, there is dust and dirt on the lens surface, but it is generally clean. I attached an eyepiece holder for astronomical telescopes to a camera lens I had and looked through it, and there did not seem to be any noticeable debris in the field of view (Photo 9).
As this is a used item, there are some scratches and signs of use. Please do not purchase if you are concerned.

[Notes]
I have made every effort to be accurate in my descriptions, but there may be oversights or inaccuracies.
The description of the condition is subjective. Please judge from the photos.
If you have any concerns, please ask questions before purchasing.

As this is a used item, the performance at the time of new purchase cannot be guaranteed. Also, support for usage methods cannot be provided. Please do not purchase if you are looking for a new or perfect item, or if you are concerned about minor details.

Thank you for your understanding and consideration before purchasing.

Immediate purchase is OK.
