Round bottom 12″ record inner sleeves are made from anti-static frosted 40 micron HDPE and are designed to protect the record while taking up less space inside the cover than a full square inner.

• 40 micron frosted HDPE
• Anti-static material
• Round bottom shape for tighter or slightly smaller covers
• 3mm lip for easier handling
• Suitable for standard-weight and heavyweight vinyl

The rounded bottom makes these a practical choice when square paper inners feel bulky or awkward in snug covers. The smooth HDPE helps the record slide more cleanly and helps reduce dust, paper scuffs, and handling wear.

These are a useful everyday replacement inner for reissues, older albums, and heavier pressings alike. If you want a neat anti-static plastic inner that stays slim inside the cover, this style is a strong all-round option.
