CryoGrip Pro Glacier - multiple versions ?

Hello there,

I bought a CryoGrip Pro Glacier 257x257 in January, and another one last week.

When I unboxed the second one, I instantly felt it was different. I double checked on Amazon and their ASIN are actually different.

The second one I bought (ASIN : B0DPFYXH14) is thicker. The first I bought (ASIN : B0DJQSTPSQ) was thinner, and "CryoGrip Pro Glacier" written in white letters on the build plate.

Could you help me figuring out if one is the upgrade of the other, or if they're just different batches ? My feeling is the second one is a first version and the second is an upgrade.

Thanks !
