Keeping it on adds to the package that must fit. SKU 10101 is described for J-cards or original sealed wrapping. SKU 10120 is for lenticular slips without booklets. Do not assume every special edition uses the same dimensions. ## Slipcover or enclosed protector? A slipcover provides slide-in access. An enclosed protector folds closed on all sides. Decide how you prefer to access your case, then choose the version that accommodates its packaging. ## What measurements should I check? Measure the width, depth and height of the edition as you intend to store it, including any retained J-card, sealed wrapping or slip. Send those measurements and the intended SKU to Barinderpal for confirmation. SKU 10120 is specified as 140.5 mm wide × 18.5 mm deep × 176 mm high . Its product reference and SKU 10101’s reference specify a 0.3 mm acid-free case . Dimensions for the other SKUs should be confirmed with Barinderpal. ## Get help with an unusual edition Email [allstarprotector@gmail.com](mailto:allstarprotector@gmail.com) or call [+1 780-807-8969](tel:+17808078969).
