I bought it to open something like a strawberry jam lid that requires a lot of force.
It's winter, so I need to make ginger tea.

It's convenient to use.
One item you need

I wish I had bought something bigger.

Every time I opened the lid of the new one, I had to search for rubber gloves, put them on, open it, take them off, it was a mess.
It's easy to open and convenient.
I opened jam jars, water bottles, and sauce bottles of different sizes and materials, and everything worked fine.
Even if the lid size doesn't perfectly match the standard in four sizes, it opens well.

As described. Fast shipping and delivery. Highly recommend the seller and the product. Thank you.
