LP Protectors are items used to protect vinyl records from dust, scratches, and other damage. The two most common types of LP Protectors are sleeves and LINERS. Sleeves are usually made of plastic or paper and fit over the record to protect it from dust and dirt. LINERS are usually made of paper and fit inside the sleeve to provide an extra layer of protection. Both sleeves and LINERS help to keep the record in good condition and extend its life.
