Size 184mm x 235mm (7.1/4" x 9.1/4" ). These are gummed so need to be dampened on the gummed part. 

Cannot guarantee they will stick as well as once did due to age so you may have to put some tape on ! 

They are slightly discoloured due to age. The box is not full but is way more than half full !

They are old /  new stock probably from the late 90's or early 2000's.
