The apology comes after the Hong Kong-based firm, Jssy, coated the craft beads in a chemical, which, when digested, can metabolise into an illicit drug.
The firm’s director, Liao Juyuan said: "The incident has given the 'Made in China' brand a negative impact during the Christmas season. I have to deeply apologise."
The firm used 1.4-butanediol to make the craft beads expand and fuse together when sprayed with water, according to the Shenzhen Entry-Exit Inspection and Quarantine Bureau.
"It chose it as a softener and organized the production and export of the toy beads," the Bureau said.
