Do I need precision balanced D8 dice to create my own multi sig seed phrases?

I'm reading https://blockchaingandalf.substack.com/p/generating-seed-phrases-with-dice and want to ensure maximum entropy when rolling. Sure I can purchase a set of ten D8 dice for ten dollars from Amazon but I'm concerned that at such a low price that they would be poorly made and imbalanced.

Should I be spending more on precision balanced D8 dice to ensure good quality rolls?
