TTDNA renders its own neutral topsheet visualisation for this brand, generated from verified construction data.

Dragon-F
The tacky hybrid sheet in the Dragon line. It keeps Chinese grip on the topsheet but uses a tensioned sponge, producing heavy spin with a high arc.
Official specifications
Friendship covering families and commercial editions are kept separate so sponge, hardness and regional versions do not create duplicate products.

Friendship publishes sponge hardness on Chinese degree scales without a named laboratory standard. TTDNA stores each value exactly as published and never converts it to Shore A, Shore C or an ESN equivalent.
Colours are only listed when an ITTF covering entry verifies them. Red and black are never assumed.
TTDNA ratings
TTDNA values are analytical 0-100 scores derived from construction, category and verified specifications. They are never official Friendship ratings and are never shown as manufacturer values.
