Generic 4x6 White Kraft Cardstock 90-Pack — 8.52 L Heavyweight Rounded Corners, Natural Matte

These are 90 premium 4" x 6" white kraft artist cards: 18pt (≈0.46 mm / ~350 GSM) heavyweight cardstock with precision rounded corners for postcards, art, and stationery.

Designed for artists, crafters, and small-batch printers, this 90-count pack of 4 x 6 white kraft cards blends a natural uncoated texture with substantial thickness. The cards are die-cut for consistent rounded corners and a clean professional edge, making them a versatile base for hand-lettering, stamping, drawing, light washes, and personalised postcards. Because the stock is extra-thick, confirm your printer supports heavyweight media or use manual/rear feed.

How sturdy is this 18pt white kraft cardstock for mixed-media projects?

The 18pt (about 0.46 mm; ~350 GSM) construction gives each card a heavyweight, durable feel that resists bending during handling and mailing. The uncoated surface accepts many dry and medium-wet media well, but very wet techniques may need testing first. These cards handle stamping, pencils, markers, and light watercolour without feeling flimsy.

• 18pt thickness: approximately 0.46 mm / ~350 GSM for robust support.
• Natural matte texture holds ink, graphite, and pigment well.
• Suitable for stamping, markers, coloured pencils, and light washes.
• Test aggressive wet media to check for warping or show-through.

Will these cards work in my printer for batch-printed postcards?

Because the stock is extra-thick, not every printer can handle it through the standard paper path. Use a rear-feed, manual-feed, or straight-through tray if available, and set your printer to a 'Heavyweight/Cardstock' mode for best results. Run a single test print to confirm feed and print quality before printing the entire run.

• Recommended: rear-feed, manual-feed, or straight paper path printers.
• Select 'Heavyweight/Cardstock' in print settings for proper ink application.
• Test-print one card to verify alignment and drying behavior.
• Avoid printers with tight, curved paper paths to prevent jams.

How do the rounded corners and die-cut edges benefit finished pieces?

Precision die-cut rounded corners give each card a polished, consistent appearance that stands up better to handling and mailing than sharp corners. The smooth edges minimize snags and reduce corner damage in envelopes or retail displays. Rounded corners also create a refined presentation for invitations, recipe cards, and small prints.

• Die-cut process ensures uniform rounded corners across the pack.
• Smoother edges resist fraying and postal wear.
• Enhanced professional look for stationery, gift cards, and postcards.
• Ready-to-use size eliminates trimming for most projects.

What creative uses are best suited to these white kraft 4x6 cards?

The cards are a practical canvas for a wide range of creative and business uses, from hand-drawn mini artworks to event RSVPs. Their uncoated face is friendly to hand-lettering and stamping, and the sturdy backing works well as small product tags or promotional postcards. Use them for practice pieces, limited-run prints, or personalised mailers.

• Custom postcards and direct-mail pieces.
• Calligraphy, hand-lettering, and stamped designs.
• Recipe cards, mini art prints, and gift enclosure cards.
• Small-scale mixed-media experiments and portfolio samples.
