Sellers of eyepiece caps?

[Zermelo]

I'm trying to find somewhere online that sells eyepiece caps.

I don't mean the 1.25" diameter ones for the barrel, I mean caps for the eye lens end. As I have been acquiring some eyepieces second hand, they don't always have caps. I've fallen back on the old green milk carton top trick, but I'd like to get some proper ones.
Of course the diameter varies, but I need some around 35mm to 40mm, ideally in soft silicone.
Eyepiece manufacturers seem to have no trouble sourcing them, but I've drawn a complete blank.
Does anyone know any outlets for these?

These folks on your side of the pond have some caps.  Agena Astro sells them on our side of the pond.  They also sell some eye guards/cups in case you need them as well.

Excellent. Many thanks, both of you.

Follow-up.

I ordered a couple of 40mm rubber caps from Nipon Scopes & Optics, as identified by @Louis D.

They arrived on the fifth working day, and they're exactly what I was after.
Thanks again.
