Squeaky – MITR (Metal base)

(Thai word means “friendship”)

1 set, there are 4 tubes with the magnet base.
Each tube, there is the one way valve in the cap.
Easy way to make the vacuum system in the tube with DIY method ( syringe or mini air vacuum)
But the valve also can release CO₂ outside the glass tube.

So Sorry, out of stock and under production now. Please wait me.
