Vac-U-Lock - Plug Duplo Fosco

Wasn't sure how the double-ended setup would actually work for us, but the Vac-U-Lock compatibility on both sides is genius — we can each pick our own attachment instead of compromising. It stays put way better than I expected too.

Frosted texture gives just the right grip without feeling sticky, and since both ends take the same attachments, my partner and I can swap things around mid-session without fumbling. Setup was quick and it’s held up fine through a few uses already.

The dual compatibility is a game-changer—we swapped between different attachments mid-session without fumbling, and the frosted texture gave just enough grip. It’s held up through a few enthusiastic uses and still feels solid.
