Needles & Grooves

Most gatefold are fine w 2.5. Some need 5.0

i thought the 2.5 stuff just meant the thickness of the sleeves (not the gap between the 2 sides of it)... which is why they sell that "ultra oversized" version

You are correct but The ultimate 5.0 is slightly larger. 2.5s IMO are nicer/clearer. For trifolds/small box sets I get my “baggy” fits elsewhere

@TheMythOfSisyphus ok so where should i go.. i have at least 2 box sets, 2 trifolds, and a couple single side triple LPs

Sleeve city for most of your needs. The 2.5 will serve your majority. Baggy fit from sleevie wonder on eBay will handle trifold and some small box sets. There are larger box set sleeves but I personally don’t sleeve all my box seta
