I bought 1L and 4L from different sellers. 1l - LLC Market. Trade, Hong Kong - not a single question, by all indications the original; 4l - OOO TK "UNITRADE", Hong Kong. Here there are questions. There are air bubbles on the labels in front and behind, well, this has already happened, it didn’t scare me much. There is no arrow on the 2023 canister indicating the month the canister was produced. She still haunts me.
