The Complete Kubrick

[kekid]

Has anyone tried the Bill Hunt's anti-static inner sleeve solution? If so, please explain how you cut the notch in the center only on one side of the sleeve. (Is the notch just a slit, a "V" or a semi-circle? Does it matter if the intention is just to insert your finger in the center hole? Also, what is the best quality source for these sleeves so that they don't crumple up? Hunt gives no details or picture.
