Hour Glass Hair Stacker

Good quality for the money

I love the large opening which makes inserting material easy. The 2 parts seem to separate when stacking. I have to hold my finger over the top to keep them together.

Works great! It's a little loose, but this doesn't seem to impact the performance. Perfect size for short to medium length hairs. A bit on the short side for bucktail, but you can make it work.
