These masks I've experienced as heck.
We had ordered two pieces for an appearance.
In the mask that we could use, the sidebands were badly sewn to the middle part, that the coarse seam herunterzottelten like a charcoal bag on the cheeks. Cutting? Better not, then the seam is on. The central part is actually not made of fabric, as can be read from the specification. It's pretty hard plastic, which expresses itself in the face. Fabric is a thin fabric, which is adhered to the outer side of the central part. The side panels / bands are made of a material which is more reminiscent of a nylon stocking on leashes. Result: When you are tying the tapes 'narrow' drawn.
Incidentally, the second mask simply had no belts, Prima!
Who runs quality control by customer complaint, must be able to live with such a review.
Conclusion: Stay away! - We were disappointed. Because we did not have time to exchange for the performance, we had to improvise.
