"For reference" sounds much better and more natural than "For consultation"
To native English speakers a manuals, books, and other documentation are "reference material." Sure, you can "consult" reference material like you could "consult" a doctor or "consult" an expert, but it's a bit more descriptive ("Reference" implies that the specific details are already there specifically to be recalled).
"Label" is much better than "Sticker"
"Stickers" are usually added to something and not part of production, like a "Great!" sticker a teacher might put on a child's graded homework to encourage the child. The art and logo on a game pak is almost universally referred to as "Label" by native English-speakers.
