100 ($24.99) or 50 ($15.99) pieces of LP inner sleeves. The same thing that has been coming with Japanese Blue Note re-issued LPs.
The material is sometimes referred to as "rice paper" but is not. It's a very soft and slick inner sleeve, for sure. A good way to use these is to put them inside the usual USA paper inner sleeve. This is a great alternative to more expensive inner sleeves, providing just as much protection.
Measures 310mm across and 305 deep.
We import these directly from Japan, no middleman. As far as we can tell, these are only made in Japan. Accept no substitutes.
