S About 69mm x 55mm(diameter: 5cm, applicable branches size: 3-9mm)MAbout 102mm x 80mm(diameter: 8cm, applicable branches size: 7-12mm)LAbout 137mm x 120mm(diameter: 12cm,applicable branches size: 12-31mm)Features1. Four small holes: Bundling through four small holes is stronger and more efficient than four corners.2. Automatic buckle: More convenient, more flexible disassembly, can be completed by one person.3. Observation port: The branch can extend from the observation port. Use black tape to seal when not in use. Prolonged ventilation will affect the rooting time.4. Water inlet: The diameter of the water inlet is increased to facilitates watering.5. Adjustable: The bottom can be adjusted reasonably according to the diameter of the branches.
