Extension Bottle Brush Jag GY

It's easy to use, so I keep buying it!

It's easy to stretch and the sponge is just the right hardness. I can also wash large water bottles without any problems. It's cheap and the cost performance is great. I buy it in bulk and keep buying it again and again.

I bought this while I was buying a water bottle. The sponge on the 100 yen store ones quickly goes soft, the metal wire is exposed, and the shape is suspiciously difficult to wash. The sponge is firm and it was really easy to wash. I should have bought this from the start

The handle is telescopic, so it's convenient to use different sizes of bottle.

I used to wash the inside of my water bottle with a regular sponge, but now I use this and it's easy and convenient to wash it clean. I wish I had used it earlier.
