The one sold in Jusco & Ace Hardware has grooves which clips on to the glass door when you close it.

Daiso ones i don't know got groove or just flat rouded rubber.

But the 1st one cost rm20-30 & you need 2 just to seal off 4 sides while Daiso cost only rm5.

But still will have some gaps around the corner where the magnets & door connectors are.

But this only dust proof, it won't stop mold & fungus from growing.

You'd need those dehumidifier & moth balls if you don't use the aircon often, or get a Dehumidifier which cost over rm1k and requires a access to dump the water. They have their water container but troublesome to dump it everyday.

anyone still want to share Henkei autobot specialist?
