Fits 1lb butter Gaylea or NoName perfectly. Only reason I didn't put as 5 star is because the shape of the lid is somewhat skewed... I understand it can't be a perfect rectangle shaped, but the side where Butter is written, is caved in. And on the backside of the lid on the left side, is also caved in a little. It makes it feel like 100% handmade because of that, or it could just be a manufacture issue.
