Very good product at a very affordable price and of course the lid closes simply, it does not have a pin, it has a hole and requires minimal additional pressure!

Soft plastic, without sharp edges. The best ampoules I have tried, especially after the change they made in the clin...r and now they have harder plastic.

Finally, after the disappointment with the Clinofar ampoules, I found a product that is just as good. The ampoules are as soft as they should be, with a good cut, and the solution is simple (without additional salts or substances like other companies add).
