JapanBargain Takoyaki Oil Brush 6-Pack, Restaurant-Grade Cotton Basting Brush with Wooden Handle for Teppanyaki Grill, Cast Iron Seasoning, Okonomiyaki & Taiyaki Pans, Heat Safe Oil Applicator

I don't recommend this Oil Brush. The main issue is that the brush material comes out during use. Save your money and look for a better-quality oil brush elsewhere.

I don’t use these for food preparation. I use these to wipe on a light coat of camellia oil on my woodworking tools. I put some oil in a small container and just leave the brush in it so that it’s ready to use.

These are insanely cool. If you want to season your cast iron and want a device that can sit on the counter, this is it. Sure, you can use paper towels, but they rip, and you can use an old towel/shirt, but those look junky. These aren't expensive and are great.

I just spray brush with vegetable oil and apply to cast iron grill grates before igniting. Would be helpful if brush handle was a little longer but as long as the first application before ignition is adequate, it's not a big issue.

Forget trying to use a silicone brush or one made with polyester hairs as they will melt when used on heated grills. These are perfect for use on Takoyaki, Teppanyaki or Taiyaki molds or flat grills that require oil to applied into small crevices.

For the price, these are fine. Any excess oil will definitely leak over time.
