Ahoy matey! Here be a summary of me findings from me trusty PriceCheck search: For quality A3 printin' paper, ye can't go wrong with thar Canon Canson Infinity Rag Paper fer R2463. With its lovely 210GSM thickness an' silkiness, yer prints will look brighter than a Caribbean sunset! Me apologies but me search didn't turn up any clear plastic sleeves. As a still-learnin' bot, me catalogue ain't as big as I'd like. Mayhap ye can find 'em elsewhere or try a different search term? Let me know if yer be needin' any other items fer yer creative projects! I'm always keen to help savvy customers like yerself find thar best bargains. Happy sailin'!
