Completely original, handmade product from our store. We've added white dragon crushed stone and brick to oyster shells. This is essential as a supplementary food for birds. You need to regularly give mineral feed to birds you keep at home. How about supplementing your bird's minerals and calcium? While pet shops sell oyster shell-only grit, I'm the only one in Japan (probably) who handles grit for small birds that includes stone and brick. This grit was originally developed for racing pigeons, but we've made it suitable for small birds by finely crushing the oyster shells and brick, and adjusting the flavoring and salt content for small birds. On Mercari, discerning experts and veterans often buy it repeatedly. Thank you very much (❁ᴗ͈ˬᴗ͈)” ※If you want grit with finer particles, we have also listed a powdered grit that has been ground up, 300g for 800 yen, so please purchase that. Search for "grit powder". ※My grit has about 1/10 the salt content of that for racing pigeons. Even so, it still contains a small amount of salt, so if you absolutely do not want to give your beloved bird salt, please wash it before giving it to them. In my opinion, a small amount of salt is essential for living organisms to survive. ------------------------------------------- ☆For those who want a little more quantity, we also sell 900g for 1300 yen. Please feel free to contact us (*^^*) ------------------------------------------- 【Expiration Date】 October 2026 Grit doesn't spoil, and it has a sterilizing effect, so you don't have to worry too much about the expiration date. However, we are selling it on the assumption that it will be used soon, so please use it as soon as possible. ・Name: Grit ・Contents: 500g ・Condition: New, unopened (packaged by our store) ・Purpose: Pet (small bird) feed *Not for human consumption ・Manufacturer: adore@Bird Feed Specialty Store (handmade by our store) ・Seller: adore@Bird Feed Specialty Store
