If you own a 3D printer, it is important to keep any unused filament dry to ensure a better build quality of your prints. Many filament types are hygroscopic which means they can draw in moisture from the air. Any moisture can lead to stringing, air bubbles, poor bed adhesion, etc. This replenishment pack comes with 6 extra replacement bags in 2 different sizes: 3pcs 30x34cm, 3pcs 26x34cm. Perfect for use with the Protech Mini Auto Vacuum Pump (TL4390) sold separately.

Poor durability, mixed sizes only, > $4 per bag
Mixed bag sizes - effectively paying over $4 per bag if you don't want both sizes. These bags are of poor durability. If you drop them when they have something in them they puncture. If replacement bags could be bought at a reasonable cost, then this would be less important, but still environmentally undesirable. As it is, if you want 1kg bags you have to pay for useless small bags as well. It is doubtful that this products its "suitable for purpose" and of "reasonable durability" as required by Australian consumer law
Should be a option for large or small bags
Should be a option for large or small bags, I purchaced 2 sets of these bags, can only can use 3 out of each pack!
Takes a few minutes to learn how to use the pump. My advice is to use a flat surface, line up the pump with the sticker, place a little pressure to seal the pump around the sticker, then suck out the air. At first, it may not appear to be working, but give it 10 or so seconds, and you should see the air start coming out. For a battery pump, it does a good job of removing the air
Don't buy
I brought these but am very disappointed, they are difficult to use the vacuum must be on for a long time before they start to suck. One of the bags popped with a obvious gash on the side so I can't even return these anymore.
50% waste
The smaller bags appear to be suitable only for the 600g reels. Given Jaycar doesn't seem to sell the 600g reels then that smaller bag is pretty-much wasted. I have started buying my bags from China because I can get the size I want.
