I love this cute Rose Gold Flare Capsule. It is so practical and nice. Very durable material which protect my Flare Calmer Pro. I recommend it. You can have it on the keys or on the bag and have your Calmer Pro always with you. Realy nice thing.
While it's great and handy, I've quite often had an earplug stuck in the upper part of the capsule: at best, you'll be looking for it for a while, but the worst case scenario is you definitely could lose it. Apart from that, it's very practical.
Great little cases for carrying your earplugs in and visible so you know where they are
