Vacuum moisture and dust defense: These storage bags reduce filament exposure to air, moisture, dust and other contaminants to help preserve PLA, PETG, ABS, TPU, ASA, PA, PC, Nylon and similar materials. Using a sealed vacuum environment limits long-term air contact and keeps spools clean and organized. Operation is straightforward: clamp the bag with a sealing clip, press the valve flat, then run the pump—the unit stops when the bag reaches the set vacuum.

Powerful 60KPa USB vacuum pump: The included electric pump delivers up to 60KPa to remove air quickly with much less effort than manual pumps. Its USB power input works with power banks, computers, USB adapters and other USB supplies for convenient use anywhere. A one-way valve and a secure zipper help hold the vacuum and reduce slow leaks over time, making these bags suited to filament storage.

Universal spool compatibility: Each large bag measures 31.5 × 33.7 cm (12.4 × 13.3 in) to accommodate a variety of spool sizes. They fit common 0.5 kg, 0.75 kg and 1 kg rolls and support standard filament diameters including 1.75 mm, 2.85 mm and 3 mm. Individual bagged spools keep your workspace neater and make filament selection quicker.

Durable PA+PE laminate, light-blocking design: Constructed from a PA+PE composite for strength and repeated use, the bags resist tears and punctures. The double-faced design pairs a transparent side for rapid identification with an opaque black side to limit light exposure. An airtight sealing structure minimizes dust and moisture ingress for reliable long-term storage.

Complete filament storage kit: The package contains 30 vacuum storage bags, one USB vacuum pump rated at 60KPa, and five sealing clips to clamp bag openings. This setup combines vacuum protection with practical accessories so you can store multiple spools compactly. It’s well suited to home makers, hobbyists, schools, studios and small print farms.

Store your 3D printer filament with this complete vacuum kit. Designed for PLA, PETG, ABS, TPU, ASA, PA, PC, Nylon and other materials, the black/clear PA+PE bags plus the USB vacuum pump and sealing clips help reduce air, moisture and dust exposure and keep spools organized.

VerdictA practical all-in-one solution for keeping filament dry and tidy. The USB 60KPa electric pump speeds evacuation and works from power banks or USB adapters, while one-way valves and a strong zipper maintain low-air conditions. Durable PA+PE construction with a black/clear dual face offers light protection plus easy identification. Good capacity for 0.5–1 kg rolls, and the 30-bag count plus clips m

Great for protecting higher-cost filaments

I started using pricier PETG and specialty materials and wanted better protection for opened rolls. The resealable bags work perfectly and the clear side shows exactly what’s inside. Having 30 bags provides lots of room for my inventory.

Cindy 5/5

Does the job — simple and effective

A straightforward product that fixes humidity and dust issues. The electric pump makes evacuation quick and the seals stay tight. I like the see-through side for identifying colors without opening every bag. I’ll buy another set when needed.

Doris Oliver 5/5

Solid vacuum bags; clear side makes life easier

These bags perform well. The pump pulls air out quickly, the zipper holds, and the bags stay compact. They take my 1 kg PLA and PETG spools with room to spare. The transparent face speeds finding the right color, while the black back looks tidy. Overall a reliable solution.
