After work, you have planned many trips to the seaside, but for some reasons, it has not been achieved. This time, you finally asked for the next week's holiday. You cherish this journey so much that you have made a lot of preparation in advance. Carry on clothes, daily necessities and commonly used electrical appliances. You will not forget to carry your own shampoo, bath gel, washing liquid and commonly used skin care products if you are careful. However, obviously, the home dosage is not suitable for travel, so you look at the two big bags you packed and worry. At this time, the travel sub bottling which has never been used since you bought it comes into your eyes. The opening of the separate bottle is very big, so you can easily put shampoo, bath gel and washing liquid into the bottle. Tighten the lid. You shake the bottle a few times. No liquid leaks out. You put the split bottle into the bag at ease. It's very small, so it's easy for you to put it into the bag. You put your favorite barbecue sauce in the last separate bottle and put it in the bag together. Your skin care products are packed in the cream bottles donated by the sub parts, which are very small and portable. You put them in your carry on compartment with the toothbrush that comes with the product. When you come to the seaside, you always like to put your hands on the beach as if you can feel something. You follow the direction of the beach to see the sea, sometimes narrow, sometimes wide, but all the things around you are reflected in the sea. When you go back to the hotel near the sea, there is not a drop of pre packed shampoo, body wash, laundry detergent and barbecue sauce.
