These record sleeves will protect your valuble record collection. Each sleeve fits nicely over single albums and fit over most gatefold double-albums. These are a quality 2 mil. plastic and will preserve your investment in records for years to come. This is a very clear plastic so that you can see your record cover very clearly, as opposed to some record sleeves that have a somewhat cloudy appearance. This is for a package of 100. Highly recommended. Also, it should be noted that when you shop at Rediscover Records you can pick up individual record sleeves at .50 cents each
