Design changes in 2022

At some point in 2022, BOTN changed the nose wire in their masks. Many people on Reddit and Twitter found the new nose wire weaker than the old nose wire. Most reports are that the newer BOTNs no longer fit as well with the weaker nose wire.

The newer, weaker nose wire appears in the BOTN masks ordered in 2022 that have "BOTN KF94 CE 2195 FFP2 NR EN 149:2001+A1:2009" embossed on the outside. Masks that just have some of these words (e.g. "BOTN KF94" appear to be the older BOTNs that have the original, stronger nose wire.
