AlcoLyzer用交換用マウスピースパック

Finally got around to replacing the old ones in my kit, and the fit on my device is snug right out of the pack. The whole set arrived sealed and clean, which is exactly what you want for something you’re about to blow into.

These are way more comfortable than the old ones I was using—the plastic is thinner but still feels durable. I like that the pack gives me plenty of spares so I don't have to worry about running out mid-week.

The fit is snug and secure on my device, so no air leaks during testing. I've gone through a few packs already and each mouthpiece feels sturdy without being too rigid. Much better than the flimsy ones I've tried before.
