🔒 Roll & Lock — No zip-lock? No problem

Did your filament spool come in a bag with no zip-lock? Filament left open absorbs moisture and ruins your prints. The Roll & Lock fixes that in under 10 seconds: no heat sealer, no clips that pop off, no vacuum bag.

📏 Six Sizes

The standard profile fits the Bambu filament bag, with a width around 30 cm (12 in). A second profile covers smaller bags in five sizes, from 10 cm to 26 cm (4 to 10 in) bag width. Use it for snacks, silica gel packs, hardware, spare parts, or any other bag that needs a reliable reseal. Need a size that is not covered? Drop a comment!

⚙️ How It Works

Slide the open end of your bag through the slot in the bar. Roll the bar tight against the bag. Fold the two end tabs down over the rolled bag. Done — almost airtight seal, zero tools, reusable forever.

For the best possible seal, try to cut the filament bag open with a maximum amount of material left over. The tighter you roll it, the tighter the seal.
