Abstract: In an aspect, a marker kit is provided, and includes a plurality of tip holders, a storage member, and an extension member. The tip holders each includes a tip holder body having a connecting portion, and a marker tip extending from the body. The storage member includes a base with a plurality of receptacles, each shaped to removably hold one of the tip holders with the connecting portion exposed. The extension member includes an extension member body for grasping. The extension member body has a securing portion and an actuatable member. The securing portion is releasably connectable to the connecting portion of each tip holder for removal from one of the plurality of receptacles. The actuatable member is for disconnecting the securing portion from the connecting portion of the tip holder that is secured to the extension member so as to release the tip holder back into a receptacle.

Abstract: One or more embodiments disclosed herein relate generally to flotation devices, and more specifically to modular flotation devices with a mechanism to removably attach to other modular devices. In one embodiments, an apparatus includes a first flotation module and a first connector coupled to the first flotation module. The first connector has a first end portion, a second end portion and a sidewall extended from the first end portion to the second end portion. The sidewall defines a plurality of circumferentially defined stepped portions configured to matingly engage a second connector of a second flotation module to couple the first flotation module to the second flotation module. The first connector is selectively operative as one of a female connector or a male connector with respect to the second connector.
