I only use this brand of ear plugs for that I can not find in the traditional trade .. They are of good quality and provided résistantw to wash them regularly. They are smaller than most other brands and are very suitable for my little ear canal size. My only regret is the former "packaging" their yellow color (flesh color can be more discreet, is not very engaging) and the small storage case for 2 cap was really convenient (luckily I kept ).
