Tyeign 100-Pack 3"X5" Ruled Index Cards in 5 Bright Colors, Double-Sided Lined Flash Cards with Metal Ring, Heavy Paper for Study, Presentations, Recipe Notes, office & Office, 1 Sticky Note

Welcome to Tyeign! We select all kinds of high-quality kitchen supplies and everyday tools and home decorations for you.

Five Color Study System: Five gentle pastel hues—pink, yellow, green, blue and orange—help visual learners categorize subjects, languages or chapter topics at a glance. With 100 cards per color, the 500-card set supports an entire semester of vocabulary, medical terminology, bar exam rules or recipe substitutions without running out of space before finals week.
Thick No-Bleed Cardstock: Each 3 x 5 in (7.6 x 12.7 cm) card is printed on sturdy 250 gsm paper that stands up to aggressive highlighting, fountain pens and even light watercolor washes without warping or ghosting to the reverse side. The double-sided ruled lines keep handwriting neat and consistent, maximizing information density while preserving legibility for quick reviews before presentations.
Smooth Ring Organization: A removable 1.2 in (3 cm) steel book-ring threads through the pre-punched corner, letting scholars shuffle, sort and study on the bus, treadmill or cafeteria line. The snag-free coil opens with a gentle squeeze yet clamps tightly to prevent cards from scattering across dorm floors or airplane aisles during last-minute cram sessions.
Portable Pocket Weight: The entire deck weighs only 4 oz (115 g) and measures 5 x 3 x 0.6 in (12.7 x 7.6 x 1.6 cm), sliding easily into lab-coat pockets, purse sleeves or glove compartments for spontaneous quizzing. The rounded corners resist dog-earing while the soft colors reduce eye strain during marathon study nights powered by coffee and determination.
Endless Learning Versatility: From kindergarten sight words to CPA formulas, these cards adapt to any curriculum—use them for memory games, public-speaking cue cards, recipe stands, wedding seating charts or DIY flip books. The affordable bulk pack equips classrooms, tutoring centers and homeoffice co-ops with a reusable tool that turns passive reading into active, confidence-building recall for learners of every age.
