After about 1 year of seldom usage it shrunk to a size 9. It is at risk of falling through and being stuck in the flask. Not acceptable!

Used to plug a hole on a rain barrel. Works slick!

We have a bottom mount water dispenser that takes 5 gallon water jugs. There's always a few cups left in the jug when the "replace jug" light comes on, so we set the old jug aside and use it later. This plug fits perfectly in the mouth of the old jug to prevent dust (and dog fur) from getting in the bottle.

It is indeed a solid stopper, and definitely creates an airtight seal. However, there appear to be some air bubbles in spots near the seal. Additionally, the edges are somewhat roughly hewn, which while not affecting the use of the stopper, the appearance is somewhat devalued.

Arrived clean and work great fro what I use them for. #10 is the smallest I would use as a stopper for a sanke keg or 2" ss tubing.

Not much to say. The stopper works and it is nice to be able to purchase a solid rubber stopper in this size range rather than the drilled stoppers that most vendors offer.
