E.C.O GRANITE is a brand launched by a manufacturer that processes and produces stone materials from around the world.
They create innovative and eco-friendly camping gear that utilizes the properties of granite.

These stone lids are individually carved from granite and finished by artisans.

This time, they were produced with the logo of Seicha Tonya Oshima Kichikichi Shoten (Tea Merchant Oshima Kichikichi Store). Available in two colors: red and black.

The cup contact surface is tapered to be compatible with commercially available Sierra cups.
It can be used with Sierra cups with a diameter of approximately 100mm to 130mm and deep-type Sierra cups.

With a heat resistance of approximately 600℃, it is also strong against heat, making it excellent for cooking such as cooking rice in a Sierra cup.

Furthermore, since stone slowly releases stored heat, it has higher heat retention than metal.
When used as a coaster after being heated, it is also effective in keeping warm items like Sierra cups from cooling down quickly.

Size: Diameter approx. 128mm / Thickness approx. 10mm
Weight: Approx. 400-450g
(Please note that there may be variations in size and weight due to manual craftsmanship.)

*When using after heating, please be careful of burns due to its high heat storage and heat retention properties.
