Flents own website. You can change the quantity. I got the 100-count bag because what I found in google made me assume they were discontinued.
I used to get them at Walmart for 50 for $8. Then it was $40 for 8.00. Then last September they switched the big containers to the orange ones, 40 pairs for $8.50. Sucky.
Now I have earplugs for the next year. 2 of the 70 count from amazon, and a 100 from Flents directly. :)
