I like them. Only issue I’ve had was self made, dropped a spool and it dented the cardboard which caused it to hang in the Sunlu dryer. Probably print some rings for my next bout of clumsiness.
I’m noticing more brands embracing cardboard spools and I’m for it
They’re easier to recycle
My only issue is when they’re full they squeak on my filament holder during printing, but I’m planning to fix that… Eventually.

Nah been getting rolls like that for a while now.
Not new but probably done for cost saving purposes.
