Which is Best for Your Wall

The best adhesive for your wall depends on factors like the wall type and the weight of the item you want to hang. If you need strong adhesion for heavier items, go for White Tack; if you prefer easy removal and reuse for lighter items, choose Blu Tack.

Factors to Consider
