The old plastic box of swimming goggles was broken and needed to be replaced. We had the double (BL SW) offered by Amazon bought - unfortunately, because two different traders. While the blue bag (the other dealers from UK) was relatively fast because we have been waiting for two weeks on the black bag (Allens of Kingsbury Swimwear). That's too long for UK. In two weeks so as shipments from China. This black bag is also useful (protects against scratches, dries quickly) and looks good. The only printed company logo will however come off soon, but that does not impair the function. The zipper on the other hand, one should very emotional deal, otherwise he jammed. He is very badly sewn.
