These Poly Sleeves are designed to protect your vinyls. Slide the 7" vinyl inside the anti-static sleeve, then slide the whole sleeve inside your paper / card sleeve to really protect your vinyl. These covers are designed to stop the dust collecting on your vinyls.
We also sell the paper/card/poly/PVC covers to really protect the vinyl as well.
If not on mainland UK there is not a surcharge as these are sent by Royalmail
