This little nifty feeding station came out of necessity! We personally feed mealworms to our jumping spiders and have bioactive enclosures. Mealworms would burrow in the substrate making it basically impossible for our spiders to catch them. This station is just big enough for mealworms to not be able to escape but your jumper can go in and grab their food or drink their water. If you plan to put a small jumper into a very big enclosure these feeding station are a must. 
we suggest using a water station converter in the feeding station (wicking rope x3 and a lid) to avoid drowning hazards.
