About filament multipacks
A multipack is two or more spools sold together, often one material in several colours. Per kilogram they are among the cheapest ways to buy filament, so this page sorts them by price per kilogram rather than by pack price.
Check the colours in the pack and the weight of each spool before you buy: packs mix 1 kg spools with smaller ones, and the cheapest pack per kilogram is only a bargain if you'll use every colour.

In stock on Amazon UK and Eryone UK right now: PLA (48), PETG (45), PLA Matte (27), PLA+ (19), PETG Translucent (3), PLA Silk (3), PLA Silk Dual/Tri (3) and PLA Rainbow (1).
Is a filament multipack cheaper than single spools?
Often, per kilogram, but not always. Compare the price per kilogram on each listing: a single spool on offer can beat a multipack, and a pack only saves money if you use all of it. Keep spare spools sealed with a desiccant until you need them.
