Why this tray solves the problem? 1.Tired of balancing drinks on uneven surfaces or rummaging through a fully covered bag? Our half-covered design allows you to keep your phone and drinks organized, turning your Bag into a portable bar - place your drinks in the cup holder and your phone in the phone holder while leaving half of the bag open to store ice or extra supplies in the bottom half of the bag for easy access to stored items. 2.Unlike bulky full-covered trays that block the entire bag, our modular system adjusts to your needs. Use one tray for partial organization, or pair two for full coverage 3.Anti-slip clip: snap-on clip keeps the tray securely in place on your Bag, and it won't fall off easily even on a bumpy car ride or a windy beach 4.Fit for BOGG BAG - Medium Tote Bag
