Don’t be fooled by imitations and knock-offs. Mack’s Pillow Soft Silicone Putty Earplugs are the original moldable silicone putty earplugs, since 1962. These earplugs mold to fit virtually any ear, and stick to form a custom airtight/watertight seal that no other earplugs can match.
I tried these in the store. When I returned I could nit find them. I tried two other brands but one wiukdnt hold water ouy well enough and the ither was so soft it plugged up mu ear tube! So I came to ebay and ordered them. Happy happy happy again!
