Diploma covers are protective sleeves designed to hold and display academic diplomas. They are typically made from materials like leather, vinyl, or cardstock and come in various sizes to accommodate different diploma dimensions. These covers often feature a clear plastic window to showcase the diploma while keeping it safe from damage. Many educational institutions, such as high schools and universities, provide diploma covers during graduation ceremonies. They serve not only as a means of protection but also as a way to enhance the presentation of the diploma, making it a more formal and celebratory keepsake for graduates.
