I have bought pins before and some were blunt, I contacted the manufacturer by email and they sent me 2 packs of 2 1/2" glass head pins that cost $25.00 per pack in Australia. I also contacted Moda Fabrics about charm packs that were not the right size and got replacements plus extra. If you don't contact them when things don't work properly they will never be able to fix the problem. Just my thoughts!
