JUST TAKE A VISINE BOTTLE AND CUT THE NIPPLE OFF THEN PUT A SHOE LACE IN IT UP THROUGH THEN THE OTHER SID BAC DOWN THRU THEN FILL IT UP WITH INK WILL POST PICS WHEN I GET THE SUPPLIES HERES THE VIDEO
My first mop was a ejuice bottle, they work great have lots of different sizes and I have plenty new ones laying around. Pretty much same as visine bottle just used a piece of scouring/scrubber pad for nib, works pretty decently and no leaks so far **Edit** The scrubber pad nib was a fail but live and learn
