Bought a few boxes for our school fundraiser and the 10mm size really makes them look chunkier than the cheap party-store strands. They came in 36-inch lengths and held up fine during the whole parade. We're already planning to order more for next year.
These strands arrived in great shape, and the 36-inch length means each one drapes well without feeling flimsy. We sold them at our fundraiser for a dollar each and they went fast, which made the whole process painless.
The 10mm size is noticeably chunkier than the standard beads I've handled before, and the 36-inch strands feel substantial when you're handing them out. We sold through our entire order in two weekends at the parade booth, and folks kept coming back for the bigger ones.
