Very good, I thought it was going to be insufficient but they go great to study quiet which is what I use them for. Very simple to place.

Order on sale 11.11. Delivery within a month in the national parcel. I have been using this for a long time.

Everything is fine, thank you to the seller. But the delivery is very long

Very nice earplugs. Accurate shipping. Ordered in 2 colors. Thanks

I haven't tried them, but it's just that it works.
