Yookeer Acrylic Corner Positioning Kit — 10 Pieces (8 Sizes) with Bone Folder & Crease Maker for Precise Cardmaking

Yookeer 10 Pieces Creative Positioning Card Corners Helpers with Bone Folder Tool is a complete acrylic corner positioning kit that helps you align, layer, and crease handmade cards precisely and quickly.

Whether you make greeting cards, invitations, scrapbooks, or other paper crafts, getting perfectly aligned corners and crisp folds changes a project from homemade to handmade. This Yookeer kit bundles eight laser-engraved acrylic corner guides in a range of widths, plus a plastic bone folder and a crease maker, so you can position elements consistently without measuring every time.

How do these corner positioning tools speed up card assembly?

Instead of marking each corner with a ruler, slip the appropriately sized acrylic corner into place and use it as a repeatable stop for stamping, layering, or trimming. The set’s multiple widths let you match cardstock thicknesses and create uniform margins across cards.

• Eight corner sizes for common paper thicknesses and border widths
• Laser-engraved size labels for quick selection
• Thin 5 mm acrylic that fits under layers without shifting
• Boxed storage with protective film keeps guides scratch-free

Which tools are included and what does each do?

The kit contains eight acrylic corner positioners, one 8.1-inch bone folder, and one 4.6-inch crease maker. The positioners act as alignment stops, the bone folder smooths and sharpens folds, and the crease maker scores or indents paper for controlled folding.

• Acrylic corners: 3/16", 1/8", 1/4", 3/8", 5/16", 1/2", 5/8", 3/4" widths
• Bone folder: compresses layers and flattens glued joints
• Crease maker: creates a consistent fold line without tearing
• Protective box and film for long-term storage

Are these tools durable and safe for my projects?

Yookeer designed the corner positioners from sturdy acrylic that resists breaking and won’t deform during normal crafting. Both plastic tools have smooth edges to avoid scratching paper and hands, and the box helps protect pieces when not in use.

• Quality acrylic resists stress and warping
• Sanded smooth edges prevent paper snags and finger scratches
• Durable plastic bone folder and crease maker for repeated use
• Laser engraving ensures size markings remain readable over time

How precise are the sizes and when should I pick each one?

The corners are laser-engraved with exact widths ranging from 1/8" to 3/4" so you can choose the right gap for your card layers or stamped borders. Select a smaller width for narrow margins and finer papers, and broader sizes for thicker cardstock or mat layers.

• Use 1/8"–3/16" for narrow borders and lightweight paper
• Choose 1/4"–3/8" for standard card layering and mats
• Pick 1/2"–3/4" for wide borders or multi-layered designs
• Thickness ~5 mm fits under most layers without lifting them

Who is this for? Crafters who make cards, invitations, or scrapbooks and want cleaner, more consistent results will benefit from this Yookeer kit. It’s especially useful for hobbyists, craft teachers, small-batch card makers, and anyone who values repeatable alignment without the fuss of constant measuring. The quantity and accessories also make it convenient for classrooms or group craft sessions where several tools are shared.
