Hi Thalia,
Thank you so much for loving our packaging and the gems! We are so sorry to hear that they didn't last as long as expected for you and your sister.
Tooth gems require a very specific application process to ensure they cure and bond properly to the tooth surface. To help you get that 2-4 week hold, we have a highly detailed step-by-step guide on our website:

A few quick, crucial tips that make a huge difference:
Keep it dry: The tooth must be completely dry before applying the bonding gel. Even a tiny bit of saliva can weaken the bond.
Curing time: Make sure to cure the UV light long enough directly over the gem to fully set the adhesive.
Please give it another try with these tips! If you're still having trouble, feel free to reply to this email directly—we'd love to help you troubleshoot and make sure you get the long-lasting look you deserve.
Best,
The Never Have I Ever Team
