Completely original, handmade product from our shop. We've added white dragon crushed stone and brick to oyster shells. This is essential for birds' supplementary food. 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 the oyster shells and brick finer and adjusted the flavoring and salt content for small birds so they can eat it. On Mercari, discerning experts and veterans often buy it repeatedly. Thank you very much (❁ᴗ͈ˬᴗ͈)” ※If you want grit with finer particles, we've listed a powdered grit that's been ground up for 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 don't 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, 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 sell it on the premise that it will be used soon, so please use it as soon as possible. ・Name: Grit ・Contents: 500g ・Condition: New, unopened (packaged by our shop) ・Purpose: Pet (small bird) feed *Not for human consumption ・Manufacturer: adore@Bird Feed Specialty Store (handmade by our shop) ・Seller: adore@Bird Feed Specialty Store
