Perle Cotton Thread Bubbles
Each handy plastic bubble holds a 10-gram ball of Prescencia perle cotton and keeps it clean and tidy.
Please note that the ball of thread fits tightly until you use up the wraps of thread around the middle of the ball. As the ball gets smaller, the thread will pull more more easily through the hole.
The cap fits snuggly on the bubble which is good because you want your thread to stay put. To save your fingers, use an old-school bottle opener to remove the top.
