It's a great way to keep stuff from getting in your stem when it's in your pocket!

Not much to add here. The product completes the mission, the stem is covered, I am at peace.

i use these while transporting my stems to hide any residual smells. works like a charm and fits pretty much all my tm2 stems like a glove (titanium, ed’s, OG tm2 short boy stem)

Thankfully I bought these when I bought the TM2 sidecar bubbler. I was lucky in buying them together because there is NO WAY TO KEEP LIQUID IN THE SIDECAR BUBBLER, to rinse and clean, if you do not have these in order to plug up the bowl of the sidecar bubbler.

To enlighten your customers, you should link this product to the Sidecar Bubbler listing and notify them in the Sidecar Bubbler product description that these are a necessity to clean the sidecar bubbler. How else are you going to keep iso alcohol in the bubbler when cleaning? Plug up the bowl with toilet paper, maybe? (That sounded a little funnier than I intended.)
