 Hi, this is Gimpa from Coloury. Today I'm happy to introduce our new products. This model is called DC2. This is the very little cute deotapes adapter. We designed this to protect your MacBook Pro and the MacBook Air. You can see here is a deotapes support, so you put it very stable to protect your deotapes support. Not hurt by any deotapes supports, you can just connect it like this, or use any deotapes supports to connect like this. Actually, this is two Thunderbolt 3 ports in this side. So any functions, there are four functions for any type C, standard like video, audio, speed or charging. Every function is fine, so a very good price for this deotapes. We support small order sale at Aliexpress Shop, or you can connect us for best price for the mass production orders. Thank you.
