Five details. Five different reasons to choose this kit.
The details that keep your filament dry, organized, and ready to print.

Patented U-Shape Design
The bag wraps the spool instead of boxing it in, removing the loose material square bags leave behind.

Upgraded Valve
Every bag has a built-in one-way valve that holds vacuum for months and reseals after each use.

Extra-Thickened Material
A durable, puncture-resistant body built for long-term reuse.

Dual Sealing Strips
The zipper is easy to press and inspect across the full width before vacuuming.

Rewritable Label
Write the brand, material, color, and date on the label area so every stored spool stays identified.
Everything included in the U-shape storage kit.
Everything that arrives in the box, so you know exactly what to expect.

U-Shape Vacuum Bags
Patented U-shaped vacuum bags with printed label dial — 10, 20, or 30 depending on the kit you select.

Desiccant Packs
One silica-gel desiccant pack per bag to absorb the moisture sealed in with each spool.

USB Auto Vacuum Pump
A rechargeable auto pump with USB charging cable — one press draws each bag down in seconds.

2 Sealing Clips
Two reusable sealing clips that glide across the zipper for an even, secure close.
Simple steps that help extend the lifespan of every bag.
These quick checks reduce unnecessary stress on the valve, zipper, and welded edges before the first vacuum cycle.
Inspect each bag
Check the surface, welded edges, zipper, and valve before placing a spool inside.
Charge the pump
Give the USB pump a full charge before its first use for consistent suction.
Keep the zipper clean
Remove dust and filament fragments before pressing the seal closed.
Stop when compact
Do not continue vacuuming after the bag has formed firmly around the spool.
Final answers before checkout.
Quick answers about compatibility, package contents, reuse, and product care.
Does this kit include a vacuum pump?
Yes. Every kit includes the USB rechargeable auto vacuum pump, desiccant packs, and 2 sealing clips.
What makes the U-shape different?
The patented shape hugs the spool, so there is less loose material, a tighter seal, and a cleaner shelf profile.
Which spool sizes fit?
The U-shaped bags are sized for 250 g, 500 g, and 1 kg filament spools.
How long does the vacuum hold?
The one-way valve holds vacuum for months. If a bag softens over time, re-vacuum it in seconds.
Can the bags be reused?
Yes. Open the zipper carefully, inspect the bag and valve, reseal it, and vacuum again.
How many bags come in a kit?
Choose a 10, 20, or 30 bag kit — desiccant packs and the pump are included in every kit.
