Review (1/5): Don't buy
These are the worst tape ins I have ever purchased. I've been installing my own tape ins for 4 years now and I almost always order them off Amazon I typically stick with the same few companies but saw that these were 40 pieces (100 grams) instead of 20 pieces in a pack for about the same price of 20 pieces (50 grams). There is no way there is a 100 grams of a hair here, they are extremely thin and I could see all of the breakage before I even removed them from the pack, they are also at least two inches shorter than they are supposed to be. Very disappointed. and I am still waiting on another package of them I would be cancelling the order but I needed them for this weekend and won't have enough time to order from somewhere else.
