I reordered these magnets after a 3 year hiatus, and the salesperson who answered the phone looked up my past order easily. The price had even gone down! I have her my credit card and the product arrived two days later! Great product, great service! I love Indigo Instruments

These small magnets are exactly the right size and shape for my purposes. The hole allows me to sew the magnet to the end of my leather tube easily. I will be reordering!
