Master Series by XR Brands: advanced BDSM gear and fetish equipment. Bondage, restraints, electro play, sensation toys, and domination accessories for experienced kinksters.
The range we stock. 90 Master Series products across every major BDSM category: gags, hoods and masks (Disguise Open Mouth Hood, Dark Inhaler Gas Mask, Ass Face Mouth Gag, Face Fuk Strap On series); chastity cages (Detained 2.0, Dark Chamber); anal trainers and dilators (Dark Droplets, Expansion Anal Dilator Set, Ass Holster Plug Harness, Ass Max Plug, Butt Slut, Bitch Silicone Dildo, Dirty Words Plug Set); cock and ball gear (Ball Stack Stretcher, Fat Dick Enhancer); nipple clamps and suckers (Adorn, Affix, Black Max); spreader bars and restraints; impact toys (whips, paddles, canes, crops); and large furniture pieces like the Free Standing St. Andrew's Cross and Bareback Submission Horse.
What Master Series is known for. Depth and seriousness. The brand sits firmly in the advanced bracket. Gear is built for sustained use rather than novelty, with metal hardware where most brands use plastic, leather and neoprene where many use vinyl, and full sized furniture pieces few competitors carry. The product line covers every category an established BDSM player needs from a single source.
Materials and care. Materials vary across the range: medical grade silicone, leather, neoprene, polished steel, and aluminium depending on the item. Wash silicone with warm soapy water; wipe leather with a damp cloth and condition periodically. Use water-based lube with silicone toys; silicone lubes degrade silicone. Store metal pieces dry to prevent corrosion.
Choosing. Beginners should usually start with a different brand. Master Series suits players with at least some experience, particularly anyone moving from beginner restraints to advanced gear. The Detained 2.0 chastity cage and Dark Droplets anal trainer set are the most accessible entry points within the range.
Plain unbranded packaging on every order, billed as TLC Ltd. Free UK delivery over £50.
