This may help...or it may not...
I use the "st.tropez" box from beauty boxes.com and have EVERYTHING to do with my acrylics in there. I keep all my cotton wool/tools in those bags the old minx used to come in! They are soooo handy! For all my polishes I keep them in a large "tackle box" off eBay. All my shellac is in a seperate beauty box off eBay that fits into a large bag (about the size of a Tesco for life bag) but its pink
so I carry my shellac + lamp over my shoulder in 1 bag! My nail art I keep in a small tackle box of eBay (when I say tackle boxes I mean like item number 221138084916) and I take the shelves out, they fit the pump bottled from Cnd in perfectly! And as for Mani and pedi I got it all in 280824208812 (that's not the biggest 1 but it was the 1st one on the list so u would have to write down all the measurements of all the similar boxes and get the biggest 1! So I think that's about it really. If there is anything else u need to no I hope I can help u with it x
