A packed bowl and a bag do not mix. These elastic silicone caps stretch over the top of a glass bowl and hold everything in place, so nothing ends up loose in a pocket, a backpack or the back of a drawer.
In the box: two bands — one black, one red.
How it fits
This is a universal stretch fit, not a threaded size. The band goes over the outside of the bowl, so it works across a range of bowl shapes and diameters. If you have been shopping by 10mm, 14mm or 18mm, that is the joint measurement where a bowl seats into a downstem, and it does not apply to a cover that sits on top.
If you need more than two
The same maker sells a five-band multi-colour bundle — blue, black, pink, green and red — which is the one to get if you have several pieces or you lose small things. The two-pack here is the black-and-red version.
Why we listed it
Almost every silicone cap sold in this space is really a cleaning plug: a multipack meant to seal a downstem and joint so you can shake solution through the piece without it leaking. Useful, but a different job. This one is built for the narrower task of covering a bowl that is already packed, which turns out to be a hard thing to find sold on its own.
