I apologize, but I will ship it without cleaning the surface stains, so please only purchase if you understand and accept this.
Regarding shipping, I will place the Jaricon bag in a paper bag or similar packaging if available. If not, I apologize, but I will attach the shipping label directly to the bag and send it.

This listing is for one 20kg bag of Jaricon. However, I have another unopened 20kg bag in stock, as well as a partially used bag of about 5kg (please note this is an estimate as I cannot weigh it due to circumstances). If you wish to purchase multiple items, I may be able to offer a discount of a few hundred yen. However, please be aware that shipping carriers have a 30kg limit per shipment, so it may not be possible to combine shipping.

This material is stronger than cement and can be used for temporary reinforcement of holes, although it may not be a permanent solution.

Please consider this offer.

The following information is from online research and is for reference only.

Jaricon (gravel concrete) is much stronger than cement alone. Cement is a powdered substance that acts as a binder. On its own, it has low strength and is prone to cracking, so it is not used as a structural material.
Jaricon (concrete) is made by mixing cement with water, sand, and gravel (coarse aggregate). The gravel acts as the bones, providing very high compressive strength and durability.
The strength differences between the materials are as follows:
Cement paste: A mixture of only cement and water. It has the lowest strength.
Mortar: A mixture of cement, water, and sand. It is stronger than cement paste, but inferior to concrete because it lacks gravel.
Jaricon (concrete): A mixture of cement, water, sand, and gravel. The gravel acts as aggregate, providing the highest strength.
