One size 15 silicone sac, made from 100% silicone. These sacs will not break down or release any sulfur compounds as it ages. Ideal for celluloid pens with excellent color. Please note: Price is per sac. Pen sacs are measured in 64ths of an inch diameter. Most sacs will need to be trimmed prior to use and are intentionally made longer than necessary.
I get these to keep my 1920's-1930's pens from discoloring. Once they go dark, they don't come back!

I have been looking for these.
They are harder to find than the regular latex sacs and are great for pens which are prone to discoloration.

I bought this to keep in my box for my next project (whatever that may be). I hope I get to use it soon!

Size 15 Silicone sac
Very nice thus far. I have only used a couple of them on a couple of pens and they seem much more sturdy and easier to put on than the rubber sacs.

Small for what I needed
Grabbed this for a slim(not petite) Sheaffer Balance. It fit, but just barely. It jiggles around noticeably in the barrel. But hey that's on me(well and Richard Binder's site for recommending this size.) That said, it does its job and it does it well, so I can't complain too much. Will be going for a #16 next time I deal with one of them.

When you need a better Sac than latex
For those Grail vintage pens you want to use the best replacement sac. This is it.

This silicone sac is pliable, effective, and simple. Good work
