the build plate is a very gritty buildtak stuck on top of a g10 surface, and i really liked it. there was no better surface for my PolyLite PC. it would stick super well and came off easily.
I can't seem to find it anywhere on amazon or aliexpress. They all sell the smoother buildtak, which rips easily whenever i use it. however, it's an old ender 3 (from 3 years ago) so maybe thats why i can't find it anymore.
Do you guys know where you can get another one?
