Arma Bianca - T-shirt, mugs, badges, clear files, Ani-Art

Azumaker - My favourite manufacturer; most of the goods I’ve bought are from this manufacturer; it sells mainly wall scrolls, clear files, and keychains (PuniColle!); most of its clear files and wall scrolls uses visuals from the latest magazine (e.g. Megami Magazine); mainly targeted to the male audience, but do offer merchandises for the female audience

Cospa - Mainly sells apparels such as T-shirt, Jackets, Tote Bags, Messenger Bags; also sell Pass Cases, Smartphone Covers, Keychain (Tsumamare), and wall scrolls. Made merchandises for both gender.

Curtain Damashii - as its name implies, it sells curtains, but only available at their web store. It also sells wall scrolls and bed sheets which can be ordered from any online store such as AmiAmi and Hobby Search. Sometimes merchandises of a specially illustrated art are sold only through this manufacturer.
