Sliding sleeve / coffee sleeve

Sliding sleeve
Sliding sleeve

From the regular coffee shop, there is cup sleeve for hot coffee or tea, however in real world, sleeve is not thick enough to cut heat from hot drink. Therefore, coffee shop uses two cups for customers. This is not eco-friendly! It uses paper cup twice more and usual and will waste energy twice. There is handle or griped paper sleeve, which is already existed but these were inconvenience and not satisfied other customers who don't like handle paper sleeve. So we introduce ecofriendly IN/OUT type paper cup sleeve. In/out type paper sleeve will give customer two options to choose for individual’s taste.
