What are the two ends for?

One end removes trapped air bubbles from a filled jar. The other measures headspace between the food and the lid.

Is it safe for mason jars?

Yes. The plastic body is designed to be gentle on jar walls and won't scratch the glass.

Does it work with any jar size?

It is made for standard mason jars. The slim end fits through the jar mouth on regular and wide-mouth jars.

Is it dishwasher safe?

The material is plastic; hand washing in warm soapy water is the safe choice to keep it in shape.

Do I still need a jar lifter and funnel?

Yes. This tool only handles debubbling and headspace. A funnel, lid wrench and jar lifter are separate canning tools.

Is it worth it over a chopstick?

A chopstick removes bubbles but does not measure headspace. This tool does both, which saves a step on each jar.

Our take on the Mainstays Canning Bubble Remover & Headspace Tool for Mason Jars

This is a two-ended plastic canning tool for mason jars. One end slides down the inside of a filled jar to release trapped air bubbles; the other measures headspace before the lid goes on. It suits water-bath and pressure canners who want one small tool instead of a chopstick and a ruler. Compared with single-purpose bubble poppers, it folds two prep steps into one and is gentle on jar walls, though it is plastic rather than metal and won't match the heft of steel canning tools.
