Does NOT fit in 5mm bead.  The tip is very large in comparison to other extensions.
The product is very thick and the hair is soft but the i-tips don't fit in the 5mm beads. We had to remove the silicone from the beads to get the tips in.  I was very disappointed.  However I've had the hair in over a week and it looks pretty good. I did have a lot of slippage which I expected since we had to remove the silicone. And the company sent me 2 correct boxes and one incorrect(tape in instead of i-tip and wrong color).  Be sure to order in enough time in case of error in shipping. The hair on the left is what my salon ordered and fits in the beads without any issue the one on the right is from this company.
