I love this glue shaker! This really helped me to use my glue properly. I worried that I didn't shake my glue enough but this really helps me to get the most out of the products I already have! I also especially appreciated the additional attachment heads to the shaker. There are multiple attachments to allow for different size bottles to be shaken. Also there's a fan attachment if you want to use the shaker as a fan. This is very convenient as a lash tech that's on the go and works out of a mobile kit.
