These needles are, in a word, awesome! Truly. I thought “acrylic, meh ..ok, they’ll be durable at least.” But oh my are they so much more! They are weirdly flexible in the best way. I’m working on a cable sweater with worsted yarn knit at a pretty tight gauge (US5 needles) and my hands were getting so sore with my Karbonz (plus, the cable broke out of the housing so, thhptt) and my HiyaHiya sharps are short and not quite the right tool for the project. These babies flex so my fingers don’t hurt, they’re smooth allowing the stitches to slip nicely and the tips feel nice against each other. Plus, they’re colorful and cute, and come with all the regular cables and even one to make a 47” circumference. Freakin awesome when working larger sized garments, am I right? And they are So! Economical! It’s legit bananas ! So much so that I just bought a second pair for my “emergency kit”. Thank you Premier Yarn for offering such a fantastic product at such an incredibly affordable price! I feel I should add that I also have top dollar high quality needles to compare to and I’m truly with this set!
