瑞士采购需求：led 霓虹灯带，led 霓虹灯带，派对和特殊场合

I'm interested in the silicone neon flex light you offer, specifically the waterproof variant designed for both indoor and outdoor decorations. I would like to know if you provide any compatible accessories, such as power supplies, connection cables, clamping mechanisms, or end caps. These components are crucial for my application. Additionally, could you share the estimated shipping time to Switzerland? I'm also looking for pricing information on ordering one or more rolls of 50 meters each. Just to confirm, are the rolls indeed 50 meters long? I appreciate your assistance and look forward to your response.
