good product

performs as advertised.

United States
A must have for printer filament.

This works amazing for sealing filament. Just a note, it works best if you place on the floor or other hard surface to vacuum out air.

United States
Works well

Forms a good seal and is quick and easy to pump air out of the bag.

Great for storage.

They work great for storing filiment and have a one way valve for removing the air that looks like it's just a sticker but holds the vaccum just fine.Almost all filiment is hydroscopic so if you 3d print and don't have a dry cabinet/room you should grab a box of these.

United States
Works great

Works very good once I moved to a table(flat solid object to place bag on). Seals filament up great, like when it arrives form factory. Have sealed 4 bags so far.

United States
Good quality.

Bags and pump seem of good quality. An inexpensive solution to protect my pla filament.

Works great, but should have included a vacuum attachment!

Just got this and have only used 4 bags. So far 1 bag does not hold vacuum and the other 3 have been great. One complaint would be that they should supply a vacuum adapter so your not killing yourself removing the air with the manual pump. I swap filament often so manually using pump is tiresome. Otherwise it��s been great!

United States
great item

work great and as described

United States
Great solution for multiple spools of filament

The bags are easy to use but require the use of a separate closing tool (included). This is a good solution for me because I have several partial spools of filament. For me it takes about 30 seconds to **** the air out of the bag. The seal holds well. Even after a couple of weeks I don��t notice any air leaking.
