The ThirtyThreeRooms x SHOSU DIY SPH can be put in your favorite inflatable!
We developed this item in close cooperation with our friends from ThirtyThreeRooms and Valentine did a tutorial on how to install it in your favorite toy.
We changed the valve to a dual-action one-way valve! So either you add pressure by putting in air or you can add temperature to the SPH by putting in warm water.
The sizes are ±20cm deep and the connecting rim of the DIY SPH has a width of 20cm.
