I absolutely love Invisibobble® because their spiral hair ties and Spunchies are less damaging, tracessless (almost), hygienic, non-soaking (they are made of polyurethane = artificial resin) and durable. When my invisibobble is not in my hair I keep it around my wrist to always have access to it (finally a hair tie I don't lose or break!).
I prefer a very dark (and opaque) color (like Power in True Black 4260285373237) as clear and light-colored hair spirals can get tinted overtime and look dirty, and I also had some with the colored thread inside and the thread broke.
If it is too stretched and/or twisted I use heat (placing in it boiling water for a few minutes) and it helps (but it never shrinks back to its pre-use size); unfortunately even if SLIM Invisibobbles look prettier at first, they stretch and get twisted more than ORIGINAL and POWER and you may need heat after each use while an ORGINAL needs less, and POWER almost never needs it.
I have thin and straight hair but I use a POWER daily and if I need an occasional cuter look on my hair or wrist I go for a SLIM or a SPRUNCHIE. ORIGINAL is nice but kinda useless when you have the other styles.
I wish they had more adult opaque colors and matte, metallic or holographic effect, or even scented spirals in their permanent offer. Would be nicer too if they were seamless or if the welding was improved (on some spiral ties it's not smooth at all). Less packaging would be great as well or reusable/compostable.
