Why U-shape

Designed around the spool

U

Fitted lower profile

Rounded lower corners follow the circular spool naturally — less loose film, tighter seal.

30%

Thicker construction

Upgraded material improves puncture resistance in everyday storage and handling.

20%

Upgraded valve

An improved one-way valve holds vacuum longer between checks.

Writable areas

Mark material, color, date, or project directly on the bag — four label zones.

FAQ

Choose without guessing

The two most common questions are which path to choose and what fits — both answered here.

Should I choose the complete kit or bags only?

Choose the complete kit if you need a pump, desiccants, and sealing clips. Choose bags only if you already own compatible accessories.

What is included in the complete kit?

20 or 30 U-shape bags, matching desiccant packs, one electric 60 kPa pump, and two sealing clips.

Which bags-only quantity should I choose?

10 for a small collection, 20 for a typical multi-material setup, 30 for large collections and print farms.

Do the bags fit common 1kg spools?

Yes — designed for common 1kg filament spools, and they also work with many 250g and 500g sizes.
