These locs look amazing. I am 5’7 and the 20inches come to my belly button when stretched out. The loop at top of the loc wasn’t that hard find or open. Yes, the locs will stick together and occasionally knot up by the curl, but not excessively. That’s to be expected with synthetic hair. Very light weight to wear. I’ve ordered 4 packs of 1b and 2 packs of 1b/30 for highlights. I only used 5 of the 6 packs for full coverage. I did individuals around the perimeter with the knotless method and cornrows in the middle with traditional crochet technique. Great buy and will buy again! They don’t carry this brand at my local beauty supply.
