Love 129 for many scents๐ If I get a scent that 129 will not take well ,most of the time I can use the scent with the 4630&4625 blend. I always wait for a shipping discount code and grab a couple of cases at a time , otherwise ship is very costly to South,Tx. I sometimes add just a tiny bit of 4630 to get a creamier melt ,works for me . I read this tip on here awhile back ,makes a nice tart in appearance . I love many of CW Ultimate & Bold fragrance oils as well. I used to love TCS tart shreds ,but now getting a completely different wax will definitely keep me from buying their wax .I just wished the wax would not change in between shipments ,such a waste of time & money .Not sure what the issue is with TCS on the tart blend ,but would love to find out .If anyone can help us out on this subject ,please chime in .
