They are certainly pliable, since they are made of wire. Which means they will bend but they will not break. If a wire crocheted item gets squished or deformed in any other way, you can always restore it's shape. Don't be afraid to stretch, squeeze, twist and sculpt them as if they were play-doh. If a tube necklace gets flattened, roll it between your palms and stretch it lengthwise, repeat. Any shape is restorable.
