Grill Ball - The Source of Good Things I purchased this in March of this year from Belle Maison, but it turned out I couldn't use it with my grill, so I am selling this unopened, brand-new item. The following is the information listed on Belle Maison's website: ● Set includes: 1 bag of zeolite (500g) ● Main material: Zeolite ● Made in Japan ● Price: 800 yen (tax included) ※ The recommended amount of Grill Ball to use is for grill grates that are approximately 21cm or larger. If the size is less than 21cm, please reduce the amount used. ※ The replacement time is when the surface of the Grill Ball becomes black with grease, when it starts to smell, or when it stops absorbing grease. ※ It can be used in grills that do not require water, as long as the drip tray is at least 1cm deep. I will pack it in a bubble-wrap envelope and ship it via Mercari delivery service.
