This futuristic ring is designed to look and feel incredible, making a visual statement while compressing the package just right.\u003c\/p\u003e\n\u003cp\u003eMade with the same featherweight 3D-printed nylon and satin finish as our iconic chastity cages, the Mk1 is the perfect complement to our \u003ca href=\"https:\/\/kink3d.com\/collections\/cobra-chastity-kits\" title=\"KINK3D Cobra Chastity Kits\" target=\"_blank\"\u003eCobra\u003c\/a\u003e and \u003ca href=\"https:\/\/kink3d.com\/collections\/kink3d-viper-chastity-kits\" title=\"KINK3D Viper Chastity Kits\" target=\"_blank\"\u003eViper\u003c\/a\u003e cages.

It’s light enough to practically defy gravity, and ergonomically contoured with a 5 mm backward curve at the bottom to hug the body and give room for the balls.\u003c\/p\u003e\n\u003cp\u003eWhen things get heated, the Mk1 is also ready for action. It’s been carefully shaped with arousal in mind, with a recessed top to minimize any downward pressure on erections.\u003c\/p\u003e\n\u003cp\u003eThe Mk1 Cock Ring is designed to be worn around the penis and testicles, sitting flush with your pubic area (similar to a chastity base ring). If you're having trouble putting it on, we recommend pushing one ball through at a time and then coaxing your penis through last.\u003c\/p\u003e\n\u003ch2 style=\"text-align: left;\"\u003e\u003cstrong\u003eSizing\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eOur \u003ca href=\"https:\/\/kink3d.com\/pages\/size-guide-mk1-cock-rings\"\u003ecomplete Mk1 size guide\u003c\/a\u003e is a good place to start!\u003c\/p\u003e\n\u003cp\u003eThe Mk1 is available in eight sizes, from 40 mm to 54 mm. Note: These sizes refer to horizontal space. Each Mk1 ring has an extra 3 mm of vertical space to reduce pressure under the scrotum.

Please keep in mind that a chastity cage partially constrains erections, whereas a cock ring enhances erections, causing everything to swell. If you go too tight, your Mk1 ring could be uncomfortable (or even unsafe) when you get hard.\u003c\/p\u003e","brand":"DI","offers":[{"title":"40mm","offer_id":44059662352610,"sku":"MK1-401S-BLK","price":50.0,"currency_code":"USD","in_stock":true},{"title":"42mm","offer_id":44059662385378,"sku":"MK1-421S-BLK","price":50.0,"currency_code":"USD","in_stock":true},{"title":"44mm","offer_id":44059662418146,"sku":"MK1-441S-BLK","price":50.0,"currency_code":"USD","in_stock":true},{"title":"46mm","offer_id":44059662450914,"sku":"MK1-461S-BLK","price":50.0,"currency_code":"USD","in_stock":true},{"title":"48mm","offer_id":44059662483682,"sku":"MK1-481S-BLK","price":50.0,"currency_code":"USD","in_stock":true},{"title":"50mm","offer_id":44059662516450,"sku":"MK1-501S-BLK","price":50.0,"currency_code":"USD","in_stock":true},{"title":"52mm","offer_id":44059662549218,"sku":"MK1-521S-BLK","price":50.0,"currency_code":"USD","in_stock":true},{"title":"54mm","offer_id":44059662581986,"sku":"MK1-541S-BLK","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0523\/3659\/1047\/files\/CRMk1-halopic.png?v=1690247843"},{"product_id":"kink3d-duo","title":"KINK3D Duo","description":"\u003cp\u003eIntroducing the KINK3D Duo™: our first multi-person cage!\u003c\/p\u003e\n\u003cp\u003eMade with the same PA12 nylon as our legendary Cobra and Viper chastity cages, Duo is designed and manufactured to withstand the forces of an intimate tug of war.\u003c\/p\u003e\n\u003cp\u003eWhether you like sensual connection or devious predicament bondage, Duo is destined to be a favorite in your toy collection.
