Lasts at least 5 years Made from 100% Medical Grade TPE(Thermoplastic Elastomer) from Germany Made in New Zealand. One Tree Planted with Each Sale. Only Irish stockist We recommend a shallow punchdown fold for Hello Cups We say ‘shallow’ because the key is to make sure the punch doesn't go below the letters on the side of the cup. Once you've nailed the fold, insert your Hello Cup. Once it pops open, give it a gentle tug to help it form a seal and you’re good to go.  If it’s in correctly and is the right size, you shouldn’t get any leakage. Like most things in life, you might need to practice a bit until you’ve got the hang of it. You can leave menstrual cups in for up to 12 hours. As a guide, on heavier days you might want to remove it every three or four hours. On light days you can leave it for up to 12 hours. To remove your Hello Cup, feel for the base of the cup. Give it a gentle squeeze – this helps to break the seal – and pull down slowly. Once it’s out, simply tip the contents down the loo, rinse (or wipe if there’s no tap handy) and reinsert. Easy! Once your period is over, we recommend you sterilise your Hello Cup either by using a 1/4 of a sterilisation tablet in a glass of water. You can also give it a quick 3 minute boil on the stove (don’t let the bottom of the cup touch the bottom of the pan though).
