Tanden bleken - Navulling

My teeth have stayed noticeably brighter since I started using this refill, and the packaging is compact enough to toss in my gym bag without taking up space. The refill cartridges click in easily, so I didn’t have to fiddle with the old kit at all.

I was worried the whitening effect would fade without buying a whole new kit, but this refill keeps my teeth just as bright with the same easy steps. The cartridge is quick to swap out and the gel amount feels consistent, so I'm not constantly reordering.

The refill snaps right into the same tray, so I didn't have to deal with any extra packaging or guesswork. Kept my smile just as bright as the first round, and the tubes feel like they'll last a good while longer than I expected.
